Abstract
Objective: To evaluate the efficacy and safety of a 2940 nm fractional photothermolysis laser in the treatment of acne scarring in Chinese people.

Methods: Twenty-six patients with moderate-to-severe atrophic scarring were treated with a 2940 nm-wavelength fractional photothermolysis laser.

Results: All patients had encouraging results. Both skin elasticity and moisture content increased significantly after five treatments. In post-treatment evaluations, both the patients treated, as well as an independent group of physicians each scored the atrophic scar improvement as significant.

Conclusion: The 2940 nm fractional photothermolysis laser is safe and effective in the treatment of acne scarring.
