Efficacy of Combined Fractional Er:Glass and Thulium Lasers Versus Microneedling for Atrophic Acne Scars

Microneedling performed with an electronic pen and sterile disposable cartridge with 12 needles and 2mm depth, three treatment sessions at four-week intervals.

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.
