Efficacy and safety of non-surgical short-wave radiofrequency treatment of mild-to-moderate erythematotelangiectatic rosacea: a prospective, open-label pilot study

Abstract

Although various treatments have been proposed for the management of rosacea, achieving complete remission of persistent erythema remains challenging. Short-wave radiofrequency (SWRF) treatment has been shown to repair skin barriers and reduce chronic inflammation. However, limited studies have evaluated the effectiveness of SWRF treatment for erythematotelangiectatic rosacea (ETR). A prospective, open-label pilot study using SWRF therapy was conducted on 30 patients with mild-to-moderate ETR. During the first stage, the patients underwent a single, full-face treatment and were evaluated before and after the session, as well as on the 7th and 15thday post-treatment. During the second stage, ten treatment sessions were administered, and the patients were evaluated before and after the tenth session, as well as 1month after the treatment. Adverse events were recorded during each treatment session, and the patients were followed up for 3months after the last session. Twenty-eight patients completed the entire trial. On the 7th day after the single treatment, the global score (total score of flushing, persistent erythema, and telangiectasia) of ETR improved from 5.23 ± 1.09 to 4.00 ± 0.76 relative to the baseline value (p < 0.05); moreover, the overall treatment satisfaction improved from 7.27 ± 0.89 to 4.90 ± 0.91 (p < 0.05). 1month after the tenth treatment session, the global score improved from 5.30 ± 1.01 to 3.85 ± 0.93 (p < 0.05), and the overall treatment satisfaction improved from 7.13 ± 0.85 to 5.17 ± 1.19 (p < 0.05). During the 3month follow-up period, there were two cases of recurrence. Therefore, this report indicates that SWRF might be an effective auxiliary treatment for mild-to-moderate ETR.
