Introduction: With several treatment options available - including laser - atrophic acne scars are nonetheless difficult to treat. The use of fractional technology results in dermal-epidermal ablation columns, interspersed with intact skin islands, allowing selective thermal damage, effective treatment and faster recovery. The objective of the present study is to demonstrate the efficacy and safety of fractional laser use in the treatment of atrophic acne scars among the Brazilian population. Methods: An open, prospective, interventional study was carried out with patients with acne scars, without restriction regarding the gender and skin phototype. Exclusion criteria were: pregnancy, breast-feeding, presence of infections or blood dyscrasias and the use of anticoagulants. The evaluation was performed by comparing texture, appearance, and relief as observed in digital photographs. Results: Of the 30 selected patients, 24 were included in the study. An improvement was noted in the parameters evaluated in the cases that underwent fractional laser (CO2, Erbium-Glass or both). Individuals who underwent multiple treatments showed better results. All those treated with 4 sessions had improvements greater than 50%. Post-inflammatory hyperpigmentation was detected in 7 of the 24 treated patients. Conclusion: The present study showed that, when using appropriate parameters and adequate care, fractional laser-assisted resurfacing is an effective and safe method for treating atrophic acne scars in the Brazilian population.
