García PN, Andrino RL. Resurfacing of atrophic facial acne scars with a multimodality CO 2 and 1570 nm laser system. J Cosmet Dermatol 2024; 23 Suppl 1:13-18. [PMID: 38587296 DOI: 10.1111/jocd.16283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Revised: 03/03/2024] [Accepted: 03/06/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND Scarring is one of the most prevalent long-term complications of acne vulgaris and has cosmetic, psychological, and social burdens. Contemporary management programs integrate multiple modalities to best address the multiple factors underlying their development and persistence. This work assessed the impact of sequential multimodal laser therapy on acne scar geometrics and texture. METHODS Adult patients (n = 16) with Fitzpatrick skin type II-IV and presenting with facial acne scars, underwent three combination ablative (CO2), and nonablative (1570 nm) laser treatment sessions at two-month intervals. Treatment was delivered using a ProScan Hybrid applicator, with each regimen including illumination with both ablative and a nonablative lasers applied in a grid mode sequence. Scar microtopography was assessed at baseline and 6 months after the last treatment session. RESULTS At baseline, all patients had both box and rolling scars, while only three had icepick scars. Six months following treatment, mean scar volume improved from 5.7 ± 5.2 mm3 at baseline to 3.1 ± 3.0 mm3 and mean affected area improved from 165.6 ± 134.0 mm2 94.0 ± 80.1 mm2, translating to 47.0 ± 7.9% and 43.2 ± 8.6% reductions from baseline, respectively. Patients were highly satisfied with treatment outcomes, and no serious adverse reactions were documented during the course of treatment or follow-up. CONCLUSION Multimodal CO2 and 1570-nm laser treatment improved the surface profilometry of patients with atrophic facial acne scars. Customization of both treatment intervals and laser settings to cosmetic regions, scar profiles and skin phototypes may further enhance treatment outcomes and expand its applicability to additional skin deformities.

Abstract
Background: Acne vulgaris is an inflammatory disease of the pilosebaceous unit in teenagers. Acne-induced inflammation leads to acne scarring. Scholars have discussed acne scar treatments; however, energy-based devices with satisfactory outcomes remain unidentified. Objective: To measure quartile grading scale and visual analog scale (VAS) to study the difference between energy-based devices. Methods: We included randomized controlled trials that evaluated patients with acne scars. The primary outcomes were the quartile grading scale and VAS scores. We used Confidence in Network Meta-Analysis to evaluate indirectness, imprecision, heterogeneity, and incoherence. Results: A total of 26 studies met the inclusion criteria. The quartile grading scale results revealed that ablative fractional laser was significantly more effective than nonablative fractional laser (standard mean difference [SMD]: 0.516, confidence interval [95% CI]: 0.281-0.750) and radiofrequency treatment (SMD: 0.941, 95% CI: 0.540-1.342). Moreover, nonablative fractional laser was significantly more effective than radiofrequency treatment (SMD: 0.426, 95% CI: 0.049-0.802). No significant difference in VAS score was found among the devices. Conclusion: Ablative fractional laser is an effective treatment for acne scars although it is associated with more pain.

Abstract
Hypertrophic scars and keloids can have significant detrimental effects on patients both psychosocially and functionally. A careful identification of patient risk factors and a comprehensive management plan are necessary to optimize outcomes. Patients with a history of dystrophic scarring should avoid unnecessary procedures and enhance the wound-healing process using various preventive strategies. As there is no single, fully efficacious treatment modality, prevention remains the best approach in reducing aberrant scar formation. When prevention therapies fail, keloids have been shown to be respond to a variety of therapies including topical and injectable corticosteroids, 5-fluorouracil, radiotherapy, lasers, and surgical excision, all with varying efficacies. As such, management should be tailored to the individual patient's risk factors with the use of combination therapies to reduce recurrence rates. Still, keloid and hypertrophic scar therapies are widely diverse with novel treatment modalities providing alternatives for recurring lesions. Laser-assisted drug delivery, skin priming, and novel topical therapies may provide alternative options for the management of hypertrophic scars and keloids.

The Efficacy of Fractional Carbon Dioxide Laser in Surgical Scars Treatment: A system Review and Meta-analysis. Aesthetic Plast Surg 2023; 47:340-350. [PMID: 35666282 DOI: 10.1007/s00266-022-02946-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 05/09/2022] [Indexed: 11/01/2022]
Abstract
BACKGROUND Surgical scars seriously affect a patient's quality of life, and they have a strong impact on individuals. Many studies have reported the results of using fractional carbon dioxide (CO2) laser to treat surgical scars and have generally found it to be effective. OBJECTIVES We conducted a meta-analysis with the objective of evaluating and proving the efficacy of fractional CO2 laser therapy for surgical scars. METHODS We performed a search of databases including PubMed, Web of Science, Embase and the Cochrane Library. The outcomes of the meta-analysis were overall scores on the Vancouver Scar Scale (VSS) and its four dimensions (pigmentation, vascularity, pliability and height). Statistical analysis was performed using RevMan 5.4 software. RESULTS A total of ten studies were included in this meta-analysis, including six randomized controlled trials (RCTs) and four nonrandomized controlled trials (N-RCTs). In the meta-analysis of RCTs and N-RCTs, similar results were obtained, and fractional CO2 laser irradiation significantly decreased VSS scores (P < 0.00001). In addition, fractional CO2 laser irradiation also had a significant effect on scores on the pigmentation (P = 0.08), vascularity (P = 0.001), flexibility (P = 0.005) and height (P = 0.008) dimensions. Except for mild pain during treatment and temporary erythema after treatment, most patients had no obvious adverse reactions. CONCLUSION Our study found that fractional CO2 laser exhibits excellent efficacy and safety in terms of surgical scar treatment. Thus, we hope it becomes more widely available to patients with surgical scars. LEVEL OF EVIDENCE III This journal requires that authors assign a level of evidence to each article.

Abstract
Significance: Laser use has become part of the gold standard of treatment as an effective adjuvant in multimodal therapy for pathologic scarring caused by burns, trauma, acne, and surgery, as well as vascular anomalies. Understanding indications and applications for laser therapy is essential for physicians to improve patient outcomes. Recent Advances: Since the 1980s, the medical use of lasers has continuously evolved with improvements in technology. Novel lasers and fractionated technologies are currently being studied in the hopes to improve treatment efficacy, while reducing complications. Recent advancements include acne treatment with novel picosecond lasers, new hypertrophic scar therapies with simultaneous laser and intense pulsed light use, and novel systems such as lasers with intralesional optical fiber delivery devices. In addition, optimizing the timing of laser therapy and its use in multimodal treatments continue to advance the field of photothermolysis. Critical Issues: Selecting the correct laser for a given indication is the fundamental decision when choosing a laser balancing effective treatment with minimal complications. This article covers the principles of laser therapy, the preferred lasers used for the treatment of scarring and vascular anomalies, and discusses the current evidence behind these laser choices. Future Directions: To optimize laser therapy, larger randomized control trials and split scar studies are needed. Continued advancement through better randomized controlled studies will help to improve patient outcomes on a broader scale.

Abstract
BACKGROUND Facial rejuvenation by lasers that target water has been a mainstay of esthetic laser treatments for decades. Modern lasers more commonly treat a fraction of the skin surface using ablative, semi-ablative, or nonablative pulses. METHODS Twenty subjects with visible evidence of chronic photoaging on the face were enrolled in this study. All subjects received two full-face, single-pass treatments spaced 2 months apart with the superficial mode of a 2910 nm fiber laser with an estimated penetration depth of 10 μm, 25% coverage, delivered in a 15 mm × 15 mm square microbeam pattern. A blinded comparison of pretreatment and 3-month post-treatment images was performed. Evaluation of biopsy samples for laser-tissue effects was performed on three separate subjects and biopsies were harvested 1-day post-treatment, 1-week post-treatment, and 2-weeks post-treatment. RESULTS Blinded evaluation of digital images revealed an average improvement score of 25.1 ± 14.5 (mean ± SEM) or 25.1%, using an 11-point scale evaluating overall improvement in photoaging (p < 0.001). Post-treatment effects were limited to mild-to-moderate erythema and edema, and the pain was rated a 1.9 out of a maximum of 10. Histology demonstrated superficial changes in the stratum corneum and epidermis with dermal inflammation present at 1-day post-treatment and 1-week post-treatment, with a return to baseline at 2 weeks. CONCLUSIONS The 2910 nm fiber laser is safe and effective for improving mild photodamage, with minimal discomfort and downtime. Dermal inflammation results from very superficial epidermal injury and may contribute to clinical improvement.

Observation on the efficacy of 1565-nm non-ablative fractional laser combined with compound betamethasone topical application on the treatment of early scar in Chinese patients. Lasers Med Sci 2022; 37:2947-2953.

Abstract
The objective of the study was to evaluate the efficacy of combining 1565-nm non-ablative fractional laser with low-dose compound betamethasone topical application in the treatment of immature early red hypertrophic scar. We enrolled 38 cases of patients who had immature red hypertrophic scar due to surgery or trauma which are all less than 6 months old. About 28 patients were assigned to the treatment group, and 10 patients were assigned to the control group. The patients in the treatment group were all treated with 1565-nm non-ablative fractional laser with the following parameters: spot size 10-16 mm, round or square-shaped according to lesional morphology, fluence 20-35 mJ/cm2, and density 150-200 microspot/cm2. The treated area was then applied immediately with low-dose compound betamethasone through topical application. Treatment cycles were repeated every month for a total 5 months. Photos were taken before the start of the treatment, and then monthly after. Vancouver Scar Scale score was used to evaluate the scar changes; all the patients were followed up for 3 more months after the last treatment. All side effects were documented. The patients in the control group received no treatment at all. All the parameters were recorded as the same as the treatment group. The total VSS score after the combination therapy is 0.96 ± 1.53, which in comparison with prior treatment VSS score 8.86 ± 1.43, showed a significant reduction following the treatments (P < 0.001). The control group without any treatment shows VSS score 7.10 ± 0.99 at the end of the study vs VSS score 7.70 ± 0.82 at the start of the study (P > 0.05). The patient satisfaction rate reaches 89.2% after treatment, The major side effects reported include 3 patients with post-inflammatory hyperpigmentation (10.7% of patients in the treatment group), and other minor discomfort such as transient warmth, erythema, and swelling of treatment sites. The combination approach using 1565-nm non-ablative laser and low dose of local application of compound betamethasone can effectively improve the immature red hypertrophic scar with no significant side effects; this should provide our practitioners with a new weapon in fighting those hard-to-manage early scar formations.

Abstract
BACKGROUND Although there is an abundance of literature on nonablative laser and energy-based therapies for the management of skin conditions, adverse events are inconsistently addressed and range widely across studies. Fitzpatrick skin phototypes (SPTs) IV to VI are believed to be at higher risk. OBJECTIVES The aim of this study was to determine the types and rates of adverse events in nonablative laser and energy-based therapies among patients with SPTs IV to VI. METHODS Articles addressing nonablative laser and energy-based therapies for skin rejuvenation and acne scarring in patients with SPTs IV to VI that provided data on adverse events were included. The pooled prevalence of each adverse event was calculated. To determine whether age, treatment indication, SPT, and device type influenced incidence, subgroup and meta-regression analyses were performed. Heterogeneity was evaluated with the I2 statistic. RESULTS Forty-three studies were included in the meta-analysis. The sample size was 1654, and the median age of subjects was 39.4 years. The most common adverse events were postinflammatory hyperpigmentation (PIH) (rate, 8.1%) and prolonged erythema (rate, 0.6%). The rate of PIH was significantly higher for diode and erbium-doped lasers compared with intense pulsed light and radiofrequency. PIH correlated positively with SPT, laser density, and total energy delivered. CONCLUSIONS Although the overall rate of adverse events in nonablative laser and energy-based therapies for SPTs IV to VI is low, the incidence of PIH is not insignificant. Certain lasers, such as diode, Q-switched Nd:YAG, and erbium-doped lasers, tend to have higher rates of PIH, whereas intense pulsed light and radiofrequency have minimal risk. Higher SPTs and higher energy deliverance correlate positively with the incidence of PIH. LEVEL OF EVIDENCE: 4

Efficacy and safety of a dual-scan protocol for carbon dioxide laser in the treatment of split-thickness skin graft contraction in a red Duroc pig model. BURNS & TRAUMA 2022; 9:tkab048. [PMID: 34988232 PMCID: PMC8720306 DOI: 10.1093/burnst/tkab048] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 10/29/2021] [Indexed: 11/13/2022]
Abstract
BACKGROUND Fractional CO2 laser plays an important role in scar management post split-thickness skin graft by loosening the graft contracture and restoring the smoothness of the surface. However, the optimal treatment protocol remains unknown. This study applied a dual-scan protocol to achieve both releasing and ablation of contracted skin graft. We comprehensively describe this treatment method and compare the efficacy and safety between this dual-scan method and the conventional mono-scan mode. METHODS A hypercontracted scar model after split-thickness skin grafting in red Duroc pigs was established. All scars meeting the inclusion criteria were randomly divided into four groups: high fluence-low density (HF-LD), low fluence-high density (LF-HD), combined group and control group. The energy per unit area was similar in the HF-LD and LF-HD groups. Two laser interventions were performed at a 6-week interval. The efficacy of the treatment was evaluated by objective measures of scar area, release rate, elasticity, thickness and flatness, while the safety was evaluated based on adverse reactions and melanin index. Collagen structure was observed histologically. The animals were followed up for a maximum of 126 days after modeling. RESULTS A total of 28 contracted scars were included, 7 in each group. At 18 weeks postoperatively, the HF-LD and the combined groups showed significantly increased scar release rate (p = 0.000) and elasticity (p = 0.036) and decreased type I/III collagen ratio (p = 0.002) compared with the control and LF-HD groups. In terms of flatness, the combined group was significantly better than the HF-LD group for elevations <1 mm (p = 0.019). No significant skin side effects, pigmentation or scar thickness changes were observed at 18 weeks. CONCLUSIONS Dual-scan protocol could achieve superficial ablation and deep release of contracted split-thickness skin graft in a single treatment, with similar contraction release and texture improvement compared to a single deep scan. Its main advantage is to restore a smoother scar appearance. Adequate laser penetration was necessary for the release of contracted scars.

Abstract
Scars can lead to aesthetic and functional impairments. The treatment of scars requires meticulous planning and an individually adapted therapeutic strategy. A conceptual algorithm for scar treatment makes everyday clinical work easier for the practitioner and offers more safety for the patient. Based on a retrospective analysis of 1427 patients who presented for treatment of a variety of scars, we developed an algorithm for scar management and treatment. The treatments are presented using case descriptions. Additionally, an electronic search of MEDLINE, EMBASE, and ClinicalTrials.gov databases was performed utilizing combinations of relevant medical subject headings for "scar treatment", "hypertrophic scar treatment" and "keloid treatment". Reference lists of relevant articles and reviews were hand-searched for additional reports. Observed outcomes included: conservative scar therapy, minimally invasive scar therapy, and surgical scar therapy using local, regional and free flaps. With this work, we provide an algorithm for safe scar treatment. For better understanding, we have described a clinical case for each algorithm modality.

Abstract
Acne scarring is a common disfiguring complication of acne, and fractional lasers are widely applied in improving it. This study is to compare the efficacy and safety of fractional non-ablative 1927 nm thulium laser (FTL) and fractional ablative 2940 nm Er:YAG laser (FEL) in the treatment of acne scarring. Subjects with moderate or severe atrophic facial acne scarring received 3 sessions of FTL on the left side of face and FEL on the right side of face at an average interval of 4-6 weeks. Major assessments included Goodman&Baron quantitative global scarring grading system (GBS), self-rated improvement and satisfaction score. Twenty-seven subjects completed the study; for FTL side, average GBS decreased from 11.15 ± 5.04 at baseline to 7.07 ± 4.87 with an improvement percent of 36.54%; for FEL side, average GBS decreased from 10.81 ± 4.46 to 7.00 ± 4.07 with an improvement percent of 35.27%. Adverse effects include transient pain, erythema, edema, and increase of acne. No significant difference was found between two lasers. Both FTL and FEL improved atrophic acne scarring and were well-tolerated. Increase of acne during laser treatment may have a negative impact on efficacy. Trial registration number was NCT04813419 and date of registration was 19th, March, 2021, retrospectively registered.

Energy-based devices for the treatment of acne scars: 2021 international consensus recommendations. Lasers Surg Med 2021; 54:10-26. [PMID: 34719045 DOI: 10.1002/lsm.23484] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Accepted: 10/03/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND OBJECTIVES Acne scars are one of the most distressing and long-term consequences of acne vulgaris, with damaging effect on a person's physical, mental, and social well-being. Numerous treatment options are available including surgical and nonsurgical techniques, depending on the clinical presentation. Although considerable advances in the development of new treatment technologies and applications have been made in the last decade, international treatment guidelines and reimbursement schemes have not yet caught up with current knowledge and practice in many centers. The authors intend to highlight the potential utility of energy-based devices (EBDs) for acne scarring, offer recommendations for safe and efficacious treatment, and provide consensus-based EBD treatment options based on varying presentations demonstrated in a series of real-life clinical photographs. STUDY DESIGN/MATERIALS AND METHODS An international panel of 24 dermatologists and plastic surgeons from 12 different countries and a variety of practice backgrounds was self-assembled to develop updated consensus recommendations for the treatment of acne scars. A two-step modified Delphi method took place between March 2020 and February 2021 consisting of two rounds of emailed questionnaires. The panel members approved the final manuscript via email correspondence. RESULTS The manuscript includes a comprehensive discussion and panel recommendations regarding the following topics: 1. the role of EBD in mitigating and treating acne scars in a patient with active acne, 2. the use of various EBDs for the treatment of different acne scar types with special focus on commonly used laser platform such as vascular lasers, ablative fractional lasers (AFLs) and non-AFLs (NAFLs), 3. treatment combinations, and 4. acne scar treatments in skin of color. The last part comprised of 10 photos of real-life clinical cases with the panel recommendation treatment plan to achieve best aesthetic outcome. CONCLUSION Panel members were unanimous in their view that EBDs have a role in the management of acne scars, with AFLs, NAFLs, vascular lasers, and RF devices preferentially selected by most of the panel experts. EBDs are considered a first-line treatment for a variety of acne scar types and patients without access to these treatments may not be receiving the best available care for optimal cosmetic results. Future high-quality research and updated international treatment guidelines and reimbursement schemes should reflect this status.

Abstract
Background: Acne scar is a distressing psychosocial problem, and it has a negative effect on the quality of life. Although variety of approaches are available, demand of less invasive and more effective ways for their treatment is needed. Objective: This study aimed to assess and compare the clinical safety, efficacy, and tolerability of fractional carbon dioxide (FCO2) laser versus fractional microneedling radio frequency (MNRF) in the management of acne scars. Materials and Methods: This study was a prospective, observational, nonrandomized, open-labeled study of total 50 patients selected according to Goodman and Baron global qualitative acne scar grading, and they were divided into two groups of 25 each, having Fitzpatrick skin type III–V. A total of four sessions were given for both the groups at an interval of 2 months. The assessment was done by the treating physician as well as by the blinded physician. Both the subjective and the objective assessment was done at the last follow up given at second month of the fourth session. Results: The mean score of 25 patients in each group of FCO2 and fractional MNRF, decreased from 29.24 to 10.7 (i.e., 63.41%) and from 33.24 to 13.04 (i.e., 60.72%), respectively, as calculated by Goodman and Baron quantitative grading assessed by the treating physician (P = 0.0001). Grade 4 (>75%) improvement was shown by four patients and Grade 3 improvement (51%–75%) was shown by 14 patients among FCO2 group, and similarly Grade 4 (>75%) improvement was shown by three patients and Grade 3 improvement (51%–75%) was shown by 12 patients among MNRF group, as observed by a blinded physician (P = 0.689). Conclusion: Both modalities are equally effective in the treatment of acne scars; however, fractional MNRF having lesser down time and Post inflammatory hyperpigmentation (PIH) among darker skin shades, with good patient satisfaction score, makes it an efficient and safer treatment option as compared to FCO2.

Abstract
Recent advances in laser technology allowed the development of systems that improve texture, appearance and pliability of skin in acne scars (AS). Currently, comprehensive comparative studies on the efficacy of the most commonly used fractional systems in AS are lacking. Thus, the aim of this work was to appraise and compare the clinical response to erbium versus CO2 lasers in AS in the form of a meta-analysis. The databases MEDLINE, EMBASE, Cochrane library were searched. Main clinical outcomes were investigator-reported scar improvement and participant-reported scar improvement. Five studies were included in this meta-analysis. Scar improvement was similar for both types of laser in terms of investigator-reported scar improvement (RR: 0.60 95 % CI: 0.35-1.02) and participant-reported scar improvement (RR: 0.99 95 % CI: 0.79-1.25). A sensitivity analysis that excluded studies with high risk of bias found the CO2 lasers to be superior to the erbium lasers (RR: 0.47 95 % CI: 0.24-0.93): However, the subgroup analysis showed the CO2 laser not to be significantly different from either the non-ablative erbium (RR: 0.65 95 % CI: 0.34-1.24) or the ablative erbium laser (RR: 0.60 95 % CI: 0.35-1.02). The CO2 laser produced a slightly greater clinical response compared to the erbium lasers based on the physician's assessment. Overall, the two devices do not differ largely in terms of efficacy but may be complementary, with each resurfacing laser better suited for different clinical tasks.

Abstract
Despite various modalities used for treating acne scars, no single treatment modality was significantly satisfactory. We compare the efficacies of fractional Erbium: yttrium aluminum garnet (Er:YAG), 2940 nm, laser versus long-pulsed Neodymium: yttrium-aluminum-garnet (Nd:YAG), 1064 nm, laser for the treatment of acne scars. Twenty patients were treated in a randomized split-face manner. They underwent three sessions at a three-week interval. Assessment of the patient was done before each treatment and 3 months after the end of the treatment sessions. The treatment effect was evaluated objectively, according to Sharquie scores for grading scarring acne vulgaris and digital photographic assessment and subjectively, according to the patient's satisfaction. Results According to objective Sharquie scores, there were no significant differences in the response between the two types of laser used. Based on the visual analog score, there was a significantly higher score of improvement for the side irradiated with fractional Er:YAG (2940 nm) laser. Subjectively, the patients were significantly satisfied with the results on the fractional Er: YAG than on the long pulsed Nd:YAG side. Both lasers were effective, However, the improvement in appearance of acne scars was better with fractional Er:YAG laser with fewer side effects with Long Pulsed Nd:YAG laser.

Abstract
BACKGROUND Inflammation and postinflammatory hyperpigmentation (PIH) are two adverse side effects of ablative fractional CO2 laser (ablative Fr CO2 ) treatment for both rejuvenation and acne scars. AIMS To evaluate the efficacy of fusidic acid cream versus erythromycin ointment as postoperative therapy in patients who underwent ablative Fr CO2 treatment for atrophic acne scars. METHODS Sixty Chinese patients who fulfilled the study criteria were recruited and randomly assigned to an experimental group treated with fusidic acid cream or a control group treated with erythromycin ointment. Postoperative treatment lasted for 7 days in each group. Each patient had two follow-up visits at 8 and 12 weeks. In total, three patients dropped out of the study, one in the experimental group at week 8 and two in the control group at weeks 8 and 12. Baseline and postoperative inflammation and PIH were assessed by facial examination, photographs, and questionnaires. Besides, PIH was evaluated by the Hyperpigmentation Activity and Severity Index (HASI) and a five-point grading system. RESULTS Moderate-to-severe PIH was observed in both groups. However, the mean HASI score and severity of PIH in the experimental group were lower than those of the control group at weeks 8 and 12 (P < 0.05). In the control group, one patient developed postoperative abscesses and one had papules, whereas no inflammation was observed in the experimental group participants. CONCLUSION Fusidic acid cream shows promise as a common treatment after ablative Fr CO2 therapy to reduce postoperative inflammation and PIH.

Abstract
This study aimed to analyze the effectiveness and safety of ablative fractional carbon dioxide laser systems (CO2 AFL) combined with autologous platelet-rich plasma (PRP) in the treatment of acne scars through the retrieval and collection of related literature to further guide the treatment of acne scars. We searched Web of Science, PubMed, Embase, Wanfang Data, Chinese National Knowledge Infrastructure, and VIP Database. All randomized and nonrandomized controlled trials on CO2 AFL combined with PRP in the treatment of acne scars were included, and Revman5.3 systematic review software was used in the meta-analysis. Nine studies were included in this meta-analysis. The data analysis results showed that the CO2 AFL combined with PRP treatment group showed significantly better results than the pure CO2 AFL control group in terms of clinical improvement score, clinical improvement rate, patient satisfaction, and crusting period. The results of this meta-analysis showed that CO2 AFL combined with PRP in the treatment of acne scars is more effective and safer than CO2 AFL alone.

Abstract
Acne scarring is one of the most common facial skin disorders. The appropriate treatments for acne scars in patients with rosacea have not been studied. This study was designed to evaluate the efficacy and safety of non-ablative fractional 1440-nm laser (1440-nm NAFL) therapy for treatment of atrophic acne scars in patients with rosacea. In this prospective, interventional study, 32 patients with rosacea and acne scars underwent three sessions of 1440-nm NAFL therapy. Therapy efficacy, epidermal barrier function, and side effects were evaluated. Thirty patients completed and the median acne scar scores significantly reduced from 45 (30, 50) to 15 (15, 30) after three treatments (P < 0.001). The improvement score of acne scars was 2.7 ± 0.7; 22 (73.3%) were satisfied or highly satisfied. The rosacea erythema scores changed from 2.1 ± 0.4 to 1.9 ± 0.5 (P = 0.326), and flushing, burning, and stinging were not worse. The oil content after treatments was significantly reduced (P < 0.001), while there was no significant difference in other indicators of skin barrier function. The quality-of-life score decreased from 17.5 ± 3.8 to 14.1 ± 3.0 (P < 0.001). No serious side effects were observed. The 1440-nm NAFL therapy is effective in the treatment of acne scaring in patients with rosacea with little damage to the skin barrier.

Abstract
Combinations of various treatment modalities were shown to be more effective than monotherapy when treating hypertrophic scars and keloids. This study was conducted to assess the effectiveness of combination therapy with non-ablative fractional laser and intralesional steroid injection. From May 2015 to June 2017, a total of 38 patients with hypertrophic scars or keloids were evaluated. The control group of 21 patients received steroid injection alone, and 17 patients (the combined group) received 1550-nm erbium-glass fractional laser treatment and steroid injection simultaneously. The mean number of treatment sessions was statistically fewer in the combined group than in the control group (6.95 vs 5.47, P = .042). There was a significant difference in the patient's scale in the combined group (14.62 vs 22.82, P = .005); however, the observer's scale was not significantly different (17.92 vs 20.55, P = .549). The recurrence rate was 38.1% (8/21) in the control group and 35.3% (6/17) in the combined groups and showed no significant difference (P = .859). However, the mean remission period was statistically longer in the combined group (3.00 months vs 4.17 months, P = .042). Combination therapy with non-ablative fractional laser and intralesional steroid injection showed better results for the treatment of hypertrophic scars and keloids with fewer treatment sessions, better patient satisfaction, and longer remission periods.

Abstract
BACKGROUND Low-fluenced 2940-nm erbium (Er):yttrium-aluminium-garnet (YAG) resurfacing elicits ablative photothermal tissue reactions confined to the uppermost parts of the epidermis. OBJECTIVE To demonstrate the efficacy and safety of low-fluenced ablative Er:YAG laser treatment in combination with broadband light (BBL) pretreatment for various pigmentation disorders. METHODS In total, 35 Korean patients with various pigmentation disorders were pretreated with BBL, and then, low-fluenced Er:YAG laser resurfacing was performed with a beam size of 4 mm and a fluence of 1.0-1.5 J/cm2 . RESULTS An average of 1.1 ± 0.4 sessions of combined BBL and low-fluenced Er:YAG resurfacing treatment was delivered to the patients. Most post-Er:YAG scaling fell off spontaneously over 3-5 days, and most of the post-BBL crusting disappeared spontaneously over 5-7 days. At 2 months after final treatment, the mean global aesthetic improvement scale score for the clinical improvement of pigmentation lesions was estimated as 2.5 ± 0.8, and that for the improvement of overall skin tone, texture, and wrinkles was 2.8 ± 1.0. CONCLUSION Our data demonstrated that post-BBL, low-fluenced Er:YAG laser resurfacing can be used to effectively treat various pigmentation disorders in Asian patients. Further improvements in overall skin tone, texture, and wrinkles were also achieved without major side effects.

Abstract
Scars are abnormal wound responses in predisposed individuals. They occur after any kind of wound and skin inflammation in predisposed individuals. Despite their benign nature, they can be aesthetically disabling. Although several approaches have been tried in their management, most of them have produced poor results. This study aims to assess the efficacy and safety of fractional CO2 laser treatment in the management of post-burn and post-traumatic scars. One hundred consecutive patients (77 females and 23 males) affected by post-burn scars as well as post-traumatic atrophic scars were treated with monthly sessions of fractional CO2 laser treatment. Patient's response to treatment was assessed clinically as well as improvement of scars by comparing the photographs taken before treatment with those taken 6 months after the last treatment session. Changes in skin texture, surface irregularity and pigmentation were assessed on a quartile grading scale and scored individually from 0 to 4. A mean of the three individual scores was calculated and the response was labelled as 'excellent' if the mean score achieved was > 3. A score of 2-3 was labelled as good response while a score below 1 was labelled as 'poor' response. A mean of six treatments per scar were required and all patients, followed up for 1 year after the last treatment, had optimum results and no recurrence. Response to treatment was excellent in 53.75%, good in 16.25% patients, and poor in 30% patients. Fractional CO2 laser gives a very good result in the management of patients with post-burn scars as well as post-traumatic scars with minimal adverse effects.

Abstract
INTRODUCTION Acne scarring is a very common problem, which can be extensive, and may lead to significant psychosocial morbidity. Multiple types of treatments are used to ameliorate atrophic scars with varying degrees of success. This paper provides an overview of the various energy-based modalities that are commonly employed against acne scarring. OBJECTIVES AND METHODS A comprehensive literature search of papers published since 2008 was performed in order to determine the efficacy and adverse reactions of commonly used energy-based treatments against post-acne scarring. RESULTS A total of 59 relevant articles were identified covering a multitude of different devices. DISCUSSION Ablative lasers seem to achieve the highest degree of efficacy, albeit this is associated with significant pain and downtime, and the risk for long-term pigmentary changes. Non-ablative fractional photothermolysis (FP) has a much safer profile but cannot achieve as good cosmetic results. The efficacies of fractional radiofrequency microneedling and radiofrequency are slightly inferior to that of FP but offer an even safer adverse profile. Little evidence is available on the remaining devices, with larger studies required in order to reach more solid conclusions. CONCLUSION Multiple devices have been used with varying levels of efficacy and very different safety profiles. There is an overall lack of high-quality evidence about the effects of different interventions. Furthermore, no standardised scale is available for acne scarring, leading to variability in evaluation and interpretation of data in different studies.

Abstract
Introduction: Non-ablative fractional erbium-doped glass 1540 nm and fractional ablative 10600 nm carbon dioxide lasers are regarded as effective modalities for treating acne atrophic scars. In this study, we aimed to compare the effectiveness of fractional CO2 laser and fractional nonablative 1540 nm erbium doped glass laser in treating post acne atrophic scars in Egyptian patients. Methods: Fifty-eight patients complaining of moderate and severe acne atrophic scars were randomly divided into 2 groups of 29 patients each. Both groups were subjected to 4 treatment sessions with 3 weeks interval and were followed up for 3 months. In group A, enrolled patient sreceived C2 laser, while in group B, patients were treated with 1540 nm erbium glass fractional laser. Results: Clinical assessment revealed that the mean grades of progress and improvement were higher with fractional 10600 nm CO2 laser but with non-significant difference between both treatments (P = 0.1). The overall patients' satisfaction with both lasers were not significantly different (P = 0.44). Conclusion: Both fractional ablative CO2 and fractional non-ablative erbium glass lasers are good modalities for treating acne scars with a high efficacy and safety profile and good patient satisfaction. The fractional ablative laser showed higher efficacy while non-ablative laser offered less pain and shorter downtime.

Abstract
The aim of this study was to evaluate the efficacy and safety of fractional carbon dioxide laser for the treatment of acne scars. Thirty-one participants, 15 female and 16 male, whose mean age was 34.84 ± 10.94 years, were included in this prospective study. The study took place between 2012 and 2016. Participants were evaluated with the "ECCA Grading Scale" before the first session, 3 months (short-term evaluation) and 3 years after the last session (long-term evaluation). Participants received two or three treatment sessions at 4-week intervals, with a 10,600 nm fractional carbon dioxide laser with pulse energies ranging between 100 and 160 mJ, 120 spot type, 75-100 spot/cm2 density, and 30 W power. Self-assessments by the participants were done 3 months and 3 years after the last session. The mean ECCA score was 107.90 ± 39.38 before the first session, and 82.17 ± 36.23 at the time of short-term evaluation (p = 0.000). The grade of improvement at the short-term evaluation was as follows: no improvement, mild, moderate, and significant improvement for 7 (22.6%), 11 (35.5%), 9 (29%), and 4 (12.9%) of the participants, respectively. Regarding self-assessments, 80.6 and 61.3% of the participants rated themselves as having at least mild improvement at the short-term and the long-term follow-up periods, respectively. The results of this study suggest that fractional carbon dioxide laser is an efficient treatment option for acne scars. Furthermore, self-assessment results show that more than half of the participants still experience at least mild improvement at the end of 3 years.

Abstract
BACKGROUND Needleless transcutaneous pneumatic injections (TPIs) are a minimally invasive way to deliver the solution into the skin for therapeutic purposes. The suggested action mechanisms of TPI therapy include mechanical stimulation, immediate tissue shrinkage and late wound healing. METHODS Thirteen Korean patients were treated with TPI for atrophic skin disorders, including acne scars, striae albae, post-furuncle, or carbuncle scars, and horizontal wrinkles with lipoatrophy. At each TPI treatment session, a single pass was made along with the atrophic skin lesions without overlapping. Thereafter, two dermatologists objectively evaluated the clinical improvement in the lesions in the photographs via the global aesthetic improvement scale (GAIS). RESULTS One month after the final treatment, the overall mean GAIS score was 2.3 ± 0.8. Six of the 13 (46.2%) patients exhibited clinical improvement of grade 3, five (38.5%) patients grade 2 and two (15.4%) patients grade 1. The overall mean subjective satisfaction score with the TPI treatment was 2.3 ± 0.9. Six of the 13 (46.2%) patients achieved subjective satisfaction of grade 3, six (46.2%) patients grade 2 and one (7.7%) patient grade 0. CONCLUSIONS The present study demonstrated that the TPI treatment is effective and safe for treating atrophic skin disorders of varying causes in Korean patients.

Abstract
The formation of a wide range of excessive scars following various skin injuries is a natural consequence of healing. Scars resulting from surgery or trauma affect approximately 100 million people per annum in the developed world and can have profound physical, aesthetic, psychological and social consequences. Thus, scar treatment is a priority for patient and physician alike. Laser treatment plays an important role in scar management with additional support from ancillary modalities. Subsequent to part 1: Burns scars, part 2 focuses on our strategies and literature review of treatment of keloid, hypertrophic, pigmented and acne scars where lasers are used in conjunction with other measures, and illustrated with case studies.

Abstract
A recent advancement in the treatment of burn scars has been the use of the carbon dioxide (CO2) laser to perform fractional photothermolysis. In this analysis, we describe our results and patient-reported outcomes with the use of fractional CO2 laser for the treatment of burn-related scarring. We performed a retrospective study of all patients who underwent CO2 laser procedures for treatment of symptomatic burn scars and skin grafts at one accredited regional burn center. Burn injury and laser treatment demographics, as well as complications, are reported. A questionnaire was administered to all patients and included patient-reported outcome measures aimed at understanding the patient experience and their subjective response to treatment. A total of 387 CO2 laser procedures were performed on 131 patients for the treatment of symptomatic burn scars and skin grafts between October 1, 2011, and May 1, 2014 (average, 2.95 procedures/patient; range, 1-11). Average time between injury and first laser was 597.35 days (range, 60-13,475). Average time between laser treatments (when multiple) was 117.73 days (range, 22-514). There were no infections requiring treatment with oral antibiotics. Overall patient satisfaction with laser therapy was 96.7%. Patients reported reductions in neuropathic pain, tightness (contracture), and pruritus (54.0, 50.6, and 49.0%, respectively). Fractional photothermolysis utilizing the CO2 laser is a safe and effective modality for the treatment of symptomatic burn scars, donor sites, and skin grafts. Patient satisfaction with this procedure is high, and complications are low. Significant improvements in scar appearance, pliability, tightness, neuropathic pain, and pruritus were commonly reported.

Abstract
BACKGROUND Acne scarring is a frequent complication of acne and resulting scars may negatively impact on an affected person's psychosocial and physical well-being. Although a wide range of interventions have been proposed, there is a lack of high-quality evidence on treatments for acne scars to better inform patients and their healthcare providers about the most effective and safe methods of managing this condition. This review aimed to examine treatments for atrophic and hypertrophic acne scars, but we have concentrated on facial atrophic scarring. OBJECTIVES To assess the effects of interventions for treating acne scars. SEARCH METHODS We searched the following databases up to November 2015: the Cochrane Skin Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library (2015, Issue 10), MEDLINE (from 1946), EMBASE (from 1974), and LILACS (from 1982). We also searched five trials registers, and checked the reference lists of included studies and relevant reviews for further references to randomised controlled trials. SELECTION CRITERIA We include randomised controlled trials (RCTs) which allocated participants (whether split-face or parallel arms) to any active intervention (or a combination) for treating acne scars. We excluded studies dealing only or mostly with keloid scars. DATA COLLECTION AND ANALYSIS Three review authors independently extracted data from each of the studies included in this review and evaluated the risks of bias. We resolved disagreements by discussion and arbitration supported by a method expert as required. Our primary outcomes were participant-reported scar improvement and any adverse effects serious enough to cause participants to withdraw from the study. MAIN RESULTS We included 24 trials with 789 adult participants aged 18 years or older. Twenty trials enrolled men and women, three trials enrolled only women and one trial enrolled only men. We judged eight studies to be at low risk of bias for both sequence generation and allocation concealment. With regard to blinding we judged 17 studies to be at high risk of performance bias, because the participants and dermatologists were not blinded to the treatments administered or received; however, we judged all 24 trials to be at a low risk of detection bias for outcome assessment. We evaluated 14 comparisons of seven interventions and four combinations of interventions. Nine studies provided no usable data on our outcomes and did not contribute further to this review's results.For our outcome 'Participant-reported scar improvement' in one study fractional laser was more effective in producing scar improvement than non-fractional non-ablative laser at week 24 (risk ratio (RR) 4.00, 95% confidence interval (CI) 1.25 to 12.84; n = 64; very low-quality evidence); fractional laser showed comparable scar improvement to fractional radiofrequency in one study at week eight (RR 0.78, 95% CI 0.36 to 1.68; n = 40; very low-quality evidence) and was comparable to combined chemical peeling with skin needling in a different study at week 48 (RR 1.00, 95% CI 0.60 to 1.67; n = 26; very low-quality evidence). In a further study chemical peeling showed comparable scar improvement to combined chemical peeling with skin needling at week 32 (RR 1.24, 95% CI 0.87 to 1.75; n = 20; very low-quality evidence). Chemical peeling in one study showed comparable scar improvement to skin needling at week four (RR 1.13, 95% CI 0.69 to 1.83; n = 27; very low-quality evidence). In another study, injectable fillers provided better scar improvement compared to placebo at week 24 (RR 1.84, 95% CI 1.31 to 2.59; n = 147 moderate-quality evidence).For our outcome 'Serious adverse effects' in one study chemical peeling was not tolerable in 7/43 (16%) participants (RR 5.45, 95% CI 0.33 to 90.14; n = 58; very low-quality evidence).For our secondary outcome 'Participant-reported short-term adverse events', all participants reported pain in the following studies: in one study comparing fractional laser to non-fractional non-ablative laser (RR 1.00, 95% CI 0.94 to 1.06; n = 64; very low-quality evidence); in another study comparing fractional laser to combined peeling plus needling (RR 1.00, 95% CI 0.86 to 1.16; n = 25; very low-quality evidence); in a study comparing chemical peeling plus needling to chemical peeling (RR 1.00, 95% CI 0.83 to 1.20; n = 20; very low-quality evidence); in a study comparing chemical peeling to skin needling (RR 1.00, 95% CI 0.87 to 1.15; n = 27; very low-quality evidence); and also in a study comparing injectable filler and placebo (RR 1.03, 95% CI 0.10 to 11.10; n = 147; low-quality evidence).For our outcome 'Investigator-assessed short-term adverse events', fractional laser (6/32) was associated with a reduced risk of hyperpigmentation than non-fractional non-ablative laser (10/32) in one study (RR 0.60, 95% CI 0.25 to 1.45; n = 64; very low-quality evidence); chemical peeling was associated with increased risk of hyperpigmentation (6/12) compared to skin needling (0/15) in one study (RR 16.00, 95% CI 0.99 to 258.36; n = 27; low-quality evidence). There was no difference in the reported adverse events with injectable filler (17/97) compared to placebo (13/50) (RR 0.67, 95% CI 0.36 to 1.27; n = 147; low-quality evidence). AUTHORS' CONCLUSIONS There is a lack of high-quality evidence about the effects of different interventions for treating acne scars because of poor methodology, underpowered studies, lack of standardised improvement assessments, and different baseline variables.There is moderate-quality evidence that injectable filler might be effective for treating atrophic acne scars; however, no studies have assessed long-term effects, the longest follow-up being 48 weeks in one study only. Other studies included active comparators, but in the absence of studies that establish efficacy compared to placebo or sham interventions, it is possible that finding no evidence of difference between two active treatments could mean that neither approach works. The results of this review do not provide support for the first-line use of any intervention in the treatment of acne scars.Although our aim was to identify important gaps for further primary research, it might be that placebo and or sham trials are needed to establish whether any of the active treatments produce meaningful patient benefits over the long term.

Abstract
Clinical experiences with non-ablative fractional erbium glass laser therapy have demonstrated promising results for dermal remodelling and for the indications of striae, surgical scars and acne scars. So far, molecular effects on human skin following treatment with these laser systems have not been elucidated. Our aim was to investigate laser-induced effects on skin morphology and to analyse molecular effects on gene regulation. Therefore, human three-dimensional (3D) organotypic skin models were irradiated with non-ablative fractional erbium glass laser systems enabling qRT-PCR, microarray and histological studies at same and different time points. A decreased mRNA expression of matrix metalloproteinases (MMPs) 3 and 9 was observed 3 days after treatment. MMP3 also remained downregulated on protein level, whereas the expression of other MMPs like MMP9 was recovered or even upregulated 5 days after irradiation. Inflammatory gene regulatory responses measured by the expression of chemokine (C-X-C motif) ligands (CXCL1, 2, 5, 6) and interleukin expression (IL8) were predominantly reduced. Epidermal differentiation markers such as loricrin, filaggrin-1 and filaggrin-2 were upregulated by both tested laser optics, indicating a potential epidermal involvement. These effects were also shown on protein level in the immunofluorescence analysis. This novel standardised laser-treated human 3D skin model proves useful for monitoring time-dependent ex vivo effects of various laser systems on gene expression and human skin morphology. Our study reveals erbium glass laser-induced regulations of MMP and interleukin expression. We speculate that these alterations on gene expression level could play a role for dermal remodelling, anti-inflammatory effects and increased epidermal differentiation. Our finding may have implications for further understanding of the molecular mechanism of erbium glass laser-induced effects on human skin.

[PMID: 26880620 DOI: 10.1016/j.bjps.2015.12.012] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2015] [Revised: 12/03/2015] [Accepted: 12/22/2015] [Indexed: 11/17/2022]
Abstract
BACKGROUND Acne scars are common and cause cosmetic problems. There is a multitude of treatment options for acne scars, including dermabrasion, chemical peeling, and fillers, but the advent of laser technology has greatly improved the treatment of acne scars. Although several laser systems are available, studies comparing their efficacy are limited. This study compares the results of treatments using resurfacing (carbon dioxide, CO2; erbium-doped yttrium aluminum garnet, Er:YAG) versus fractional (nonablative fractional laser, NAFL; ablative fractional laser, AFL) lasers. METHODS A retrospective photographic analysis of 58 patients who underwent laser treatment for facial atrophic acne scars was performed. Clinical improvement was assessed by six blinded investigators with a scale graded from 0 to 10. Adverse events were also noted. RESULTS Mean improvement scores of the CO2, Er:YAG, NAFL, and AFL groups were 6.0, 5.8, 2.2, and 5.2, respectively. The NAFL group showed a significantly lower score than the other groups. The mean number of treatments was significantly greater in the fractional laser groups than in the resurfacing laser groups. The resurfacing laser groups had a prolonged recovery period and high risk of complications. The Er:YAG laser caused less erythema or pigmentation compared to the CO2 laser. CONCLUSIONS Although the CO2 laser, Er:YAG laser, and AFL improved the acne scars, the CO2 laser had a greater downtime. Three consecutive AFL treatments are as effective as a single treatment with resurfacing lasers, with shorter social downtime periods and less adverse effects.

Abstract
BACKGROUND While laser resurfacing remains the most effective treatment option for atrophic acne scars, the high incidence of post-treatment adverse effects limits its use. Fractional laser photothermolysis attempts to overcome these limitations of laser resurfacing by creating microscopic zones of injury to the dermis with skip areas in between. AIM The aim of the present study is to assess the efficacy and safety of fractional CO2 laser resurfacing in atrophic facial acne scars. MATERIALS AND METHODS Sixty patients with moderate to severe atrophic facial acne scars were treated with 3-4 sessions of fractional CO2 laser resurfacing at 6-week intervals. The therapeutic response to treatment was assessed at each follow up visit and then finally 6 months after the last laser session using a quartile grading scale. Response to treatment was labelled as 'excellent' if there was >50% improvement in scar appearance and texture of skin on the grading scale while 25-50% response and <25% improvement were labelled as 'good' and 'poor' response, respectively. The overall satisfaction of the patients and any adverse reactions to the treatment were also noted. RESULTS Most of the patients showed a combination of different morphological types of acne scars. At the time of final assessment 6 months after the last laser session, an excellent response was observed in 26 patients (43.3%) while 15 (25%) and 19 patients (31.7%) demonstrated a good and poor response respectively. Rolling and superficial boxcar scars responded the best while pitted scars responded the least to fractional laser monotherapy. The commonest reported adverse effect was transient erythema and crusting lasting for an average of 3-4 and 4-6 days, respectively while three patients developed post-inflammatory pigmentation lasting for 8-12 weeks. CONCLUSIONS Fractional laser resurfacing as monotherapy is effective in treating acne scars especially rolling and superficial boxcar scars with minimal adverse effects.

Abstract
BACKGROUND Few studies have examined the role of fractional lasers in individual acne scars (ice-pick, box car, rolling) using objective assessment tools in darkly pigmented skin. OBJECTIVE To evaluate the effect of 1,540-nm fractional lasers on individual acne scars. METHODS AND MATERIALS A prospective interventional study was conducted in 35 patients using a 1,540-nm fractional laser. Six sessions were performed with four passes per session and a dose varying from 70 to 100 mJ to maximize the DWR. A self-devised objective assessment tool with dose settings to optimize the depth-to-width ratio (DWR) and a visual analog scale (VAS) were used to count individual atrophic scars. Final results were assessed 6 months after final laser treatment. RESULTS Acne scar reduction efficiency was used to validate the improvement of individual scars, a meaningful difference was considered as 51% or greater improvement. The boxcar scars (52.9%) responded better than the rolling (43.1%) and ice-pick scars (25.9%), with statistically significant improvement (p < .05) seen in boxcar scars after four sessions. Overall VAS scores revealed significant improvement (p < .001). CONCLUSION Using an objective evaluation tool, an erbium-doped glass laser was found to improve atrophic acne scars, markedly so for boxcar and rolling scars. The VAS score overestimated improvement because of its subjective nature.

Abstract
BACKGROUND Treatment of acne scars with ablative fractional CO2 laser appears to be an effective and well-tolerated treatment. However, so far the influence of treatment interval has not been evaluated. OBJECTIVE To evaluate whether treatment of acne scars with fractional CO2 laser resurfacing at 1-month interval achieves better results with no difference in the occurrence of adverse effects, than treatment given at 3-months interval. METHODS Patients (n = 13) with symmetrical atrophic acne scars on right and left sides of the mid-face and lower-face were randomized to two fractional CO2 laser treatments at 1-month versus 3-month intervals. Blinded on-site evaluations were performed 1 and 6 months after the last treatment on 10-point scales. Endpoints were scar atrophy, patient satisfaction, and adverse effects. RESULTS Pre-operatively, acne scars were moderately atrophic (5.86 ± 1.87). After treatment acne scars appeared with less atrophy on both treated sides 1 month postoperatively (1-month interval 1.96 ± 1.23, P < 0.0001; 3-months interval 1.82 ± 1.08, P = 0.0006) and 6 months postoperatively (1-month interval 1.56 ± 1.24, P = 0.0021; 3-months interval 1.33 ± 1.66, P = 0.0002). The treatment interval did not influence the improvement of scar atrophy at any time postoperatively (P = 0.81). Patients were moderately and equally satisfied with the treatment result on facial sides (P = 0.93). Postoperative adverse effects were minor and not influenced by the treatment interval. CONCLUSIONS Fractional CO2 laser resurfacing improves atrophic acne scars and a treatment interval of either 1-month or 3-months does not seem to influence the improvement of scar atrophy nor the occurrence of postoperative adverse effects.
