Efficacy and Safety of a 1064-nm Nd:YAG Picosecond Laser Versus a 1927-nm Fractional Laser for Atrophic Acne Scars.

Overview

Atrophic acne scars are common disfiguring skin problems, especially in the Asian population prone to Post-inflammatory Hyperpigmentation (PIH), and their treatment is highly challenging. 1064 nm microlens array picosecond laser (P-MLA) based on optomechanical effect and 1927 nm segmented thulium laser (FTL) based on photothermal effect are two emerging therapeutic techniques, but there is a lack of strict clinical evidence for direct comparison in the Asian population. This study aims to directly compare the clinical efficacy, safety and tolerability of 1064 nm P-MLA and 1927 nm FTL in the treatment of atrophic acne scars in the Asian population through a randomized, half-face controlled, evaluator blind trial.
