Efficacy of Combined Fractional Er:Glass and Thulium Lasers Versus Microneedling for Atrophic Acne Scars
Sponsor: University of Nove de Julho
Summary
The purpose of this study is to compare two treatments for acne scars on the face. The study will test whether fractional lasers (Erbium:Glass and Thulium) lead to better improvement in acne scars than microneedling.
Official title: Randomized Controlled Trial Comparing Fractional Erbium:Glass (1540-1550 nm) and Thulium (1927 nm) Lasers Versus Microneedling for the Treatment of Atrophic Acne Scars

Interventions
Microneedling
Microneedling performed with an electronic pen and sterile disposable cartridge with 12 needles and 2mm depth, three treatment sessions at four-week intervals.
Fractionated Er:Glass Laser combined to Fractionated Thulium Laser
Fractional Erbium:Glass laser will be applied first, focused on scarred areas (50 mJ, 15 ms e 100 PPA) , followed immediately by fractional Thulium 1927 nm over the full face (10 mJ, 1 ms e 100 PPA), three treatment sessions at four-week intervals.
