Efficacy of Fractional Radiofrequency in the Treatment of Erythematous Capillary Rosacea: A Split-Face Study

This study assessed the efficacy of fractional radiofrequency (FRF) treatment for erythematous capillary rosacea in a split-face trial with 20 female participants aged 23–46. Participants received three to six treatments at 2-week intervals. Results indicated significant reductions in redness and porphyrin levels on the treated side, suggesting FRF's effectiveness in alleviating specific rosacea symptoms. Improvements were noted in skin barrier function, pore size, and capillary structures, with high patient satisfaction and minimal short-term adverse effects. However, the study's small sample size and short follow-up period limit the generalizability of the findings, highlighting the need for larger, long-term studies.
