Taylor, M. B., & Koron, N.Dermatologic Surgery : Official Publication for American Society for Dermatologic Surgery.47(4), 496–499, 2021.
Background:
Successful treatment of acne scars in ethnic skin requires procedures that are safe and effective with a low incidence of hyper or hypopigmentation postoperatively.
Aim:
In this study, the safety and efficacy of a combined treatment protocol including tumescent anesthesia, subcision, trichloracetic acid peel, and fractional erbium laser resurfacing was evaluated.
Material and Methods:
This is a retrospective study of 56 patients (22 women and 34 men) with predominantly rolling acne scars and Fitzpatrick skin Types IV–VI who were treated using a combination of tumescent anesthesia, extensive subcision, fractional ablative erbium laser, and a blending 20% trichloracetic acid (TCA) peel.
Results:
The mean improvement after a single treatment, assessed by 3 independent evaluators (2 dermatologist and 1 dermatology physician assistant), was 2.52 (SD = 1.04) on a scale of 1 to 4.
Conclusion:
The combination of tumescent anesthesia, extensive subcision, fractional ablative erbium laser resurfacing, and a blending 20% TCA peel (combined procedure) is both safe and effective in the treatment of rolling acne scars in ethnic skin types with acceptable temporary adverse effects.
