Findings from a new study demonstrated that fractional radiofrequency microneedling, a technique used in various dermatologic conditions, is a safe and effective approach for treating acne vulgaris.
Dermatologists from Kosin University College of Medicine in Busan, South Korea, examined 25 patients with moderate to severe acne. Fractional radiofrequency microneedling was conducted 3 times at 1-month intervals. Investigators assessed acne lesion count, subjective satisfaction score, sebum excretion level and adverse events. Patients were assessed at baseline and at 4, 8 and 12 weeks after the first treatment and subsequently at 4, 8 and 12 weeks after the final therapy.
The investigators found that the number of acne lesions, both inflammatory and non-inflammatory, decreased; sebum excretion and subjective satisfaction were more favorable at every time point compared with the baseline values (P<0.05).
Inflammatory lesions responded better than non-inflammatory lesions (P<0.05). Pinpoint bleeding, pain and erythema were observed, but were transient and did not warrant treatment discontinuation.
