BACKGROUND Treatment of atrophic scars using a fractional laser resurfacing technique has demonstrated favorable outcomes.
OBJECTIVE To evaluate the efficacy and safety of 2,790-nm-wavelength ablative fractional resurfacing on atrophic acne scars in Asian individuals.
METHODS Twenty participants (8 female, 12 male, mean age 26) with skin phototype IV and atrophic acne scars were treated with two sessions of 2,790-nm ablative fractional resurfacing laser at a 6-week interval. Objective and subjective (clinical evaluation by two blinded dermatologists) assessments were obtained at baseline and 1 and 3 months after the final treatment.
RESULTS At the 3-month follow-up, 70% of the participants were rated as having at least 50% to 89% improvement of scars. Mild erythema was the most common adverse effect, observed in 30% of participants, but resolved completely in an average of 5 days.
CONCLUSIONS Yttrium scandium gallium garnet ablative fractional resurfacing (2,790-nm) appears to be effective and well tolerated for the treatment of atrophic acne scars in Asians.
