Background: Acne vulgaris is a prevalent cutaneous disorder that significantly affects patient quality of life. There have been several reports of successful acne treatment using lasers. However, few studies have reported the use of radiofrequency (RF) lasers for acne. Objective: The purpose of this study was to evaluate the efficacy and safety of a noninvasive monopolar RF laser in the treatment of acne vulgaris on the face. Methods: A randomized, prospective, split-face study was performed. Eleven participants were recruited. Patients were treated with the RF laser on one half of the face and no laser treatment on the other half. Two treatments were performed at 2-week intervals. Patients returned for follow-up 2 weeks after the final treatment. Results: After 4 weeks, the lesion counts of papules, comedones, red macules, and the sebumeter measured values all significantly decreased on the treated area compared to those on untreated areas. In the photograph analysis, the grade of acne (using Cook's acne grading method) also significantly improved after treatment. Patients reported tolerable pain and mild erythema with laser treatment. However, there were no permanent adverse events. Conclusion: Treatment with the noninvasive RF laser successfully reduces acne lesions (papules, comedones, and red macules) and sebum secretion without severe adverse events.
