Abstract
Background: Fractional ablative lasers have recently been used for the treatment of skin scars. The objective of this study was to assess the efficacy and safety of the fractional erbium-doped yttrium aluminum garnet (Er:YAG) laser (2940 nm) in the treatment of skin scars. Materials and methods: A total of 9 patients (8 female, 1 male) with Fitzpatrick skin types III and IV suffering from atrophic facial acne scars were treated with a fractional Er:YAG laser for 2–5 (mean 3.3) sessions 4–6 weeks apart. One independent investigator assessed the efficacy, using standardized photographs, before and 1 month after the last treatment. The patients’ satisfaction rate was also evaluated. Results: The treatment was well tolerated by all patients without any anesthesia. The downtime was 2–3 days. All patients showed improvement in scars: excellent in 1, good in 1, and fair in 7 patients. Six patients were highly satisfied and 3 were satisfied with treatment. No adverse effect was noted. Conclusion: A fractional Er:YAG laser can deliver an effective and minimally invasive treatment for acne scars.
