No results posted yet for this study

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.

Conditions

  • Acne Scars

Interventions

DEVICE

Microneedling

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

DEVICE

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.
