Energy-based devices for the treatment of Acne Scars: 2022 International consensus recommendations.

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.

3D in vivo optical skin imaging for intense pulsed light and fractional ablative resurfacing of photodamaged skin.

The authors present a 3D in vivo imaging system used to assess the effectiveness of IPL and fractional laser treatments of photodamaged skin. Preoperative and postoperative images of patients treated with these procedures are analyzed and demonstrate the superior ability of this 3D technology to reveal decrease in vascularity and improvement in melanin distribution and calculate the degree of individual deep wrinkles before and after treatment.

Photodynamic photorejuvenation of the face with a combination of microneedling, red light, and broadband pulsed light.

BACKGROUND: High efficacy and safety, coupled with in-office, short contact protocols have made photodynamic therapy (PDT) with aminolevulenic acid (ALA) for the treatment of actinic keratoses a mainstay option over the last decade. Clinical improvement in photoaged skin has also been reported to accompany PDT treatments. The study objective was to maximize epidermal penetration and subsequent activation of ALA for the treatment of photodamaged facial skin, utilizing a microneedle roller prior to incubation and combined irradiation with red light and broadband pulsed light in a single treatment. MATERIALS AND METHODS: A full-face treatment of 21 patients was performed with 630 nm light and broadband pulsed light after multiple passes with a microneedle roller and 1-hour ALA incubation. The primary endpoint was clinical improvement, scored during two separate live assessments by three physicians blinded to previous scores, using a 5-point standardized photoaging scale. The secondary endpoint was evaluation of patient satisfaction based on a quartile scale comparing baseline to 6-month post-treatment photography. RESULTS: Statistically significant improvement was seen in the global photoaging scores, as well as sub-components of the scale (fine lines, mottled pigmentation, sallowness, tactile roughness, and telangiectasias) at 3 months as compared with baseline live assessment, and at 6-month live assessment compared with the 3 months. In addition, 90% of patients judged clinical improvement to be greater than 50% at 6 months compared to baseline photography. CONCLUSION: Use of a microneedle roller to "pre-treat" prior to application of ALA appears to be well tolerated and allows for even absorption and perhaps deeper penetration of ALA following a defined incubation period. Use of red light and broadband pulsed light allowed for deeper activation of ALA, potentially accounting for marked clinical improvement in photoaging.

Facial teleangectasias: our experience in treatment with IPL.

BACKGROUND AND OBJECTIVES: Facial teleangectasias can be a relevant cosmetic problem, which the patient usually hides with a thick layer of makeup. This study will describe the response on these vascular lesions using the intense pulsed light (IPL) source. METHODS: Five hundred eighteen consecutive patients were treated with Photoderm VL (Lumenis Ltd.). The average age of patients of various skin types (Fitzpatrick I to IV) was 48.5 years. They were subjected to a mean of 1.69 treatments (range 1-9) followed up 48 hours, 72 hours, 1 week, 3 weeks, and 1 month after each treatment. All patients were followed up after 2 months from the last treatment and the percentage of clearance was assessed by comparing pre- and post-treatment photographs. The patients also answered a questionnaire in which they expressed personal satisfaction. The physicians evaluation was also recorded on the same form. RESULTS: Patients (87.64%) presented a clearance of 75%-100%. The results appear not correlated with lesions size, age, skin type but with operator experience. Minimal side adverse effects occurred in 20% of the patients. CONCLUSION: The IPL source, Photoderm VL, can be considered an alternative or a supplement to the existing laser devices for facial teleangectasias treatment.
