Cosmeceuticals Used in Conjunction with Laser Resurfacing

Practice patterns regarding combination treatments and laser and energy based devices: A survey of American Society for Laser Medicine and Surgery Members

OBJECTIVE

The use of laser and energy-based devices (LEBD) has grown exponentially in recent years, and variations in common practices exist. Our study sought to evaluate the current practice paradigms of leaders in the field of LEBD with regard to antimicrobial prophylaxis, adjuvant topical treatments, use of laser procedures in pregnancy, and combination of procedures.

METHODS

Anonymous surveys were distributed to leading dermatologists in American Society for Laser Medicine & Surgery (ASLMS) via email.

RESULTS

Surveys were distributed to 65 ASLMS members; 37 submitted responses. Routine antiviral prophylaxis is used by 76% for fractional ablative procedures of the face, but only 27% for fractional non-ablative procedures. Routine antifungal prophylaxis was used by a minority (16%) for ablative procedures, whereas antibacterial prophylaxis was used by 68%, with varying antibiotics. Wide variations exist in skin preparation and topicals used post-laser treatment. Most respondents feel comfortable combining same-day LEBD and botulinum toxin injections, specifically vascular or Q-switched/picosecond lasers. Most respondents avoid performing LEBD during pregnancy.

CONCLUSIONS

Expert consensus in a rapidly growing field sheds light on common, reliable practices. However, even at the expert level, variations exist. Further high-quality research is needed to standardize and update guidelines.

Commentary: Facial Aesthetic Dermatological Procedures and Photoprotection in Chinese Populations

The medical literature on aesthetic dermatology has primarily focused on a light-skinned patient population, yet patients of darker skin types have different needs and priorities. In Chinese individuals, key concerns include altered pigmentation, which is perceived to age the individual, and also relates to the Chinese cultural standard of beauty of fair skin; many seek aesthetic treatment for this. Non-invasive cosmetic procedures such as lasers and injections are also gaining in popularity in the Chinese market, but this population is prone to hyperpigmentation as an adverse effect of such procedures. Considered and tailored approaches, both to primary concerns of photoaging and the side effects of cosmetic treatments, are warranted.

Cutaneous Delivery of Cosmeceutical Peptides Enhanced by Picosecond- and Nanosecond-Domain Nd:YAG Lasers with Quick Recovery of the Skin Barrier Function: Comparison with Microsecond-Domain Ablative Lasers

Picosecond or nanosecond-domain non-ablative lasers generate faster photothermal effects and cause less injury than microsecond lasers. In this study, we investigated the enhancing effect of 1064 nm picosecond- and nanosecond-domain neodymium (Nd):yttrium–aluminum–garnet (YAG) lasers on the cutaneous delivery of cosmeceutical peptides. Microsecond-domain fractional ablative CO2 and fully ablative erbium (Er):YAG lasers were also used for comparison. In the Franz diffusion cell study, pig or mouse skin was treated with a laser before exposure to palmitoyl tripeptide (PT)-1, PT-38, and copper tripeptide (CT)-1 at a concentration of 150 μM. Psoriasiform, atopic dermatitis (AD)-like, and photoaged skins were also developed as permeation barriers. The non-ablative laser elicited the ultrastructural disruption of the stratum corneum and epidermal vacuolation. All laser modalities significantly increased the skin permeation of peptides in vitro. The non-ablative laser chiefly enhanced peptide delivery to the receptor compartment, whereas the ablative laser mainly increased the intracutaneous peptide deposition. The picosecond- and nanosecond-domain Nd:YAG lasers elevated the amount of PT-1 in the receptor up to 40- and 22-fold compared with untreated skin, respectively. Laser treatment promoted peptide delivery in barrier-deficient and inflamed skins, although this enhancement effect was less than that observed in healthy skin. Fluorescence microscopy indicated the capability of the non-ablative laser to deliver peptides to deeper skin strata. The ablative laser confined the peptide distribution in the epidermis. Confocal microscopy showed that peptides penetrated the skin along the microdots created by the fractional Nd:YAG and CO2 lasers. The skin barrier function determined by transepidermal water loss suggested quick recovery when using a nanosecond-domain laser (within 4 h). A longer period was needed for the skin treated with the fully ablative Er:YAG laser (76–84 h). Nanosecond non-ablative laser-facilitated peptide delivery may become an efficient and safe approach for cosmeceutical applications.

Laser-Assisted Hyaluronic Acid Delivery by Fractional Carbon Dioxide Laser in Facial Skin Remodeling: A Prospective Randomized Split-Face Study in France

BACKGROUND AND OBJECTIVES

Combining the efficacy of ablative fractional carbon dioxide lasers (AFXL) to laser-assisted hyaluronic acid delivery (LAHAD) has not yet been studied. The objective of our study was to evaluate the safety and the efficacy of laser-assisted hyaluronic acid (HA) delivery with AFXL in facial skin remodeling.

STUDY DESIGN/MATERIALS AND METHODS

We conducted a prospective, double-blinded, randomized split-face study on 20 patients from 30 to 70 years old, with a skin phototype from I to IV. Each patient received full-face treatment with AFXL, immediately followed by the application in droplets into the fractional ablative tunnels of 1 ml of HA gel on one hemiface and 1 ml of physiological saline on the other hemiface. To evaluate postlaser aftermath, the intensity of erythema, edema, and crusts was graded. To assess facial skin remodeling, we scored the improvement of skin texture, firmness, fine lines, and skin radiance from baseline. Patients were evaluated on the 3rd and 7th day, 1st and 3rd month using clinical evaluations, photographs, and patient questionnaires.

RESULTS

We showed equivalence in postlaser aftermath between HA-treated and nontreated hemiface. Trend data analyses at the 3rd month suggested that immediate application of HA after AFXL resulted in a greater improvement in facial skin remodeling, especially for skin texture (mean score of 2.60 vs. 2.45) and skin firmness (mean score of 2.55 vs. 2.40). Skin radiance showed the best improvement, reaching almost a score of 5/10.

CONCLUSIONS

LAHAD with AFXL is a safe treatment showing promising results in facial skin remodeling. These findings need to be confirmed by a larger study to evaluate the value of LAHAD in daily clinical practice. Lasers Surg. Med. © 2021 Wiley Periodicals LLC.

Fractional carbon dioxide laser and acoustic-pressure ultrasound for transepidermal delivery of cosmeceuticals: a novel method of facial rejuvenation

BACKGROUND

This study aimed to determine the efficacy and safety of a new facial rejuvenation procedure that combines a fractional carbon dioxide (CO2) laser, an ultrasound emitter, and a cosmeceutical preparation to be applied intraoperatively.

METHODS

A split-face, double-blind randomized prospective study of 14 patients was designed, in which one half of the face was treated with a fractional CO2 laser, with the other half receiving the same laser and acoustic pressure ultrasound for transepidermal delivery of cosmeceuticals. Two semiquantitative scales and two visual analog scales were completed to evaluate the efficacy of each treatment. The results were assessed on the basis of photographs taken before treatment and then after 1, 2, and 6 months afterward. Potential adverse effects and complications were recorded.

RESULTS

Both treatments achieved significant improvements in all parameters evaluated (p < 0.001). The combined ultrasound and cosmeceutical treatment had better scores for reduced fine lines and wrinkles as well as for overall facial aging at 6 months (p < 0.01), with nearly 80 % overall improvement in facial aging. The treatment was well tolerated, and no unexpected adverse effects were observed. The majority of the patients (86 %) stated that they were satisfied or very satisfied with their results.

CONCLUSION

One session of fractional ablative CO2 laser and acoustic pressure ultrasound technology for transepidermal delivery of cosmeceuticals is an effective method for treating facial rejuvenation.
