Summary

Fractionated laser resurfacing is commonly used as a treatment for acne scarring in fair skinned individuals. This study aims to test the efficacy and safety in darker skin types. Patients are randomized to either the 10mJ 40mJ dosages and receive a total of five treatments at 17% one month apart. Improvement is judged by a dermatologist as 0-25%, 25-50%, 50-75% or 75-100%. Side effects such as pigmentary abnormalities and pain are also evaluated.

Detailed description

Background: Ablative resurfacing lasers are effective for treatment of acne scars, but they have a high risk of complications. Fractional lasers have less severe side effects but more moderate efficacy than ablative devices. Studies were performed in individuals with Fitzpatrick skin type I to VI. Objective: To determine the efficacy and safety of an erbium 1,550-nm fractional laser in the treatment of facial acne scars in Fitzpatrick skin types IV to VI. Methods: We conducted a prospective, single-blind, randomized trial in patients with acne scars (n=15), skin type IV to VI, with a 1,550-nm erbium fractionated laser. Patients were divided into two groups; one was treated with 10 mJ and the other with 40 mJ. Five monthly laser sessions were performed. A patient questionnaire was distributed.
