Avaliação comparativa do Laser de CO2 fracionado e da dermoabrasão no tratamento de cicatriz de acne

Introduction: Acne scars are common, and their treatment is challenging. Several techniques have been used to remove, reposition, and flatten acne scars to improve the appearance of the skin’s surface. More recently, fractional CO2 laser has been used to correct such scars due its good results and shorter recovery time. Objective: To evaluate and compare fractional CO2 laser vs. dermabrasion-based treatment of acne scars. Methods: Nine patients were assessed – six received fractional CO2 laser and three were treated with dermabrasion. Subjective and objective parameters were evaluated for both treatment modalities. Results: Both patient groups showed objective and subjective improvement. Conclusions: This study has demonstrated that fractional CO2 laser and dermabrasion-based treatments have similar efficacy in moderate to severe acne scars
