Abstract
Acne scarring is one of the most common facial skin disorders. The appropriate treatments for acne scars in patients with rosacea have not been studied. This study was designed to evaluate the efficacy and safety of non-ablative fractional 1440-nm laser (1440-nm NAFL) therapy for treatment of atrophic acne scars in patients with rosacea. In this prospective, interventional study, 32 patients with rosacea and acne scars underwent three sessions of 1440-nm NAFL therapy. Therapy efficacy, epidermal barrier function, and side effects were evaluated. Thirty patients completed and the median acne scar scores significantly reduced from 45 (30, 50) to 15 (15, 30) after three treatments (P < 0.001). The improvement score of acne scars was 2.7 ± 0.7; 22 (73.3%) were satisfied or highly satisfied. The rosacea erythema scores changed from 2.1 ± 0.4 to 1.9 ± 0.5 (P = 0.326), and flushing, burning, and stinging were not worse. The oil content after treatments was significantly reduced (P < 0.001), while there was no significant difference in other indicators of skin barrier function. The quality-of-life score decreased from 17.5 ± 3.8 to 14.1 ± 3.0 (P < 0.001). No serious side effects were observed. The 1440-nm NAFL therapy is effective in the treatment of acne scaring in patients with rosacea with little damage to the skin barrier.
