Abstract
BACKGROUND Nonablative lasers treat photoaged skin and stimulate new collagen formation while sparing epidermal damage. OBJECTIVE To evaluate the effectiveness and safety of nonablative fractional diode combination laser skin resurfacing treatment (1440 and 1927 nm) in mild-to-moderate photoaged skin. MATERIALS AND METHODS The entire face was treated with both 1440-nm and 1927-nm wavelengths per treatment, with a total of 4 treatments spaced 1 month apart. Follow-up occurred at 1 and 3 months post-treatment. Outcomes were improvement in the appearance of ≥1 measure of photodamage (rhytides, skin texture, dyschromia/pigment, skin radiance, pore size, and overall appearance) at the 3-month (primary) and 1-month (secondary) follow-up visits. Safety was monitored throughout the study. RESULTS Participants ( N = 28; 89% female; mean age, 40 years) experienced significant mean improvement from baseline in all measures of photodamage with combination laser treatment at 1 and 3 months post-treatment (all p < .001). No serious adverse events occurred. Post-treatment erythema and edema were minimal, and pain levels remained consistent throughout treatment. Most participants (96.4%) considered their overall appearance as improved and expressed satisfaction with treatment outcomes. CONCLUSION Nonablative combination laser skin resurfacing treatment was well tolerated and significantly improved measures of photodamage in photoaged skin across diverse skin types.

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.

Abstract
BACKGROUND Pulsed diode array laser systems are utilized extensively for various aesthetic indications such as removal of unwanted hair, treatment of vascular and pigmented lesions, and wrinkle reduction. OBJECTIVE The purpose of this study was to report and assess the experience of using a diode laser system delivering pulsed infrared laser light at the near-infrared (NIR) spectrum at wavelengths of 805 and 1060 nm. METHODS The study was a retrospective analysis of treatment outcomes in adult subjects treated at the clinic between January 2017 and April 2018 for wrinkles and pigmentation with a noninvasive aesthetic diode laser system. Subjects were treated at nominal wavelengths of 805 nm for pigmentation and 1060 nm for wrinkles reduction. Improvement in pigmentation and wrinkles, adverse events, and patient tolerability to treatment and satisfaction were evaluated. RESULTS Of 44 subjects with Fitzpatrick skin types II-IV, eight were treated for pigmentation and 36 for wrinkles. For both treatments, subjects reported tolerable pain levels. All immediate responses resolved within 48 hours post-treatment. Evaluation of treatment outcomes by two blinded evaluators demonstrated significant pigmentation clearance mean of 2.50 ± 0.15, (P < .05) in subjects treated for pigmentation, as well as significant improvement mean of 0.46 ± 0.12 (P = .005) in wrinkles in 13 subjects (41%) whose "before" and "after treatment" photographs were correctly identified by both blinded evaluators. Subjects were satisfied with the treatments. CONCLUSIONS Use of the Diode laser effectively resulted in improvement in pigmentation and wrinkles, while maintaining a high safety profile with limited downtime.

Abstract
BACKGROUND The nonablative, fractional, 1,927-nm diode laser is theoretically a safe and effective treatment for hyperpigmentation and melasma in darker skin and may potentiate topical cosmeceutical delivery. OBJECTIVE To evaluate the use of a nonablative, fractional, 1,927-nm diode laser with and without topical 2% hydroquinone (HQ) cream for moderate-to-severe facial hyperpigmentation in Fitzpatrick skin Types III-V. METHODS Forty adults underwent 4 laser treatments at 2-week intervals and were randomized to daily application of 2% HQ cream or moisturizer. Follow-ups were conducted 4 and 12 weeks after the final laser treatment. RESULTS Hydroquinone and moisturizer groups demonstrated Mottled Pigmentation Area and Severity Index improvements of approximately 50% at post-treatment Weeks 4 and 12. Blinded investigator-assessed hyperpigmentation and photodamage improved significantly for both the groups at post-treatment Weeks 4 and 12. Subject satisfaction improved significantly in both the groups by post-treatment Week 4. Although investigator-rated Global Aesthetic Improvement Scale scores were significantly better in the HQ group at post-treatment Week 12, satisfaction was higher among those using moisturizer. No adverse events were noted. CONCLUSION The nonablative, fractional, 1,927-nm diode laser produced significant improvement in hyperpigmentation in Fitzpatrick skin Types III-V by 4 weeks, with maintenance of results at 12 weeks after treatment even without HQ.

Abstract
CONTEXT Since antiquity, Pistacia lentiscus L. (Anacardiaceae) fruit oil (PLFO) has been used as a remedy for primary health care such as burn treatment. OBJECTIVE This study assesses the healing effect of PLFO on CO2 laser fractional burn in a rat model. MATERIALS AND METHODS The study was carried out on 18 adult male Wistar rats. A second-degree laser burn (wound area = 2.2 cm2) was inflicted in the dorsal region by the application of CO2 fractional laser within the following parameters; Energy level: 25 MJ and Depth level: 4. After applying laser, the rats were divided into three groups: the first was treated with saline solution, the second with a reference cream 'CYTOL BASIC®' (0.13 μg/mm2) and the third with PLFO (0.52 μL/mm2). All treatments were topically administered for eight days. The healing effect was assessed using macroscopic, histological and biochemical parameters. RESULTS After eight days, the higher percentage of wound healing contraction was observed among the PLFO-treated group (100%) followed by the 'CYTOL BASIC®' treated group (61.36%) and untreated group (32.27%). During the treatment, the PLFO-treated group showed less erythema, less crusting/scabbing, higher general wound appearance scores and a high content of collagen (220.67 ± 7.48 mg/g of tissue) than the other groups. DISCUSSION AND CONCLUSION The current study has shown, for the first time, the healing effect of PLFO on CO2 laser fractional burn. Their wound healing effect could be attributed to their antimicrobial, anti-inflammatory and antioxidant effects.

Abstract
BACKGROUND AND OBJECTIVE Fractionated photothermolysis (FP) has revolutionized modern laser technology. By creating selective columns of microthermal damage, fractionated devices allows for greater treatment depths to be achieved without the prolonged downtime and risk of complications seen in traditional fully ablative laser resurfacing. Fractional resurfacing is a proven method to treat a variety of cutaneous conditions. In the Caucasian patient, a wide range of devices and treatment settings can be utilized safely and effectively. However, ethnic skin requires special consideration due to its unique pigmentary characteristics and clinical presentations. In this review article, we detail the current indications and strategies to optimize results and mitigate complications when utilizing fractional resurfacing for the Asian patient. METHODS A review of the MEDLINE English literature was conducted on fractionated laser devices studied in the Asian population. Articles included describe non-ablative devices including fractionated erbium glass, thulium fiber, diode, and radiofrequency devices; and ablative devices including fractionated carbon dioxide (CO2 ) laser, erbium yttrium aluminum garnet and yttrium scandium gallium garnet (YSGG) laser. These data were integrated with the expert opinion of the authors. CONCLUSION Taking into account the unique characteristics and cosmetic concerns of the Asian population, fractional resurfacing can be considered a safe and effective option for the treatment of atrophic and hypertrophic scarring, and photorejuvenation in ethnic skin types. Select cases of melasma may be treated with fractionated non-ablative devices, but utilized with caution. The predominant complication associated with fractional resurfacing for these conditions is post-inflammatory hyperpigmentation (PIH) and rebound worsening of melasma. A greater number of treatments at lower density settings and wider treatment intervals typically produce the lowest risks of PIH without compromising treatment efficacy. Lasers Surg.
