A 2940 nm fractional photothermolysis laser in the treatment of acne scarring: a pilot study in China.

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.
