Comparison of Fractional Picosecond 1064-nm Laser and Fractional Carbon Dioxide Laser for Treating Atrophic Acne Scars: A Randomized Split-Face Trial.

Background: To date, no studies have compared the fractional picosecond 1064-nm laser (FxPico) and fractional carbon dioxide laser (FxCO2) for the treatment of acne scars.

Objective: To compare the efficacy and safety between FxPico and FxCO2 for treating facial atrophic acne scars.

Materials And Methods: Twenty-five Asian patients with mild to moderate atrophic acne scars underwent single sessions of randomized split-face treatment with FxPico and FxCO2.
