Non-ablative bipolar and monopolar radiofrequency devices have been shown to be effective for the treatment of facial wrinkles. Recently, novel fractionated microneedle radiofrequency (FMRF) devices have been introduced. The aim of this study was to evaluate the clinical effectiveness and safety of FMRF for the treatment of periorbital wrinkles. Eleven women, aged 34-59 years, with periorbital wrinkles underwent three sessions of FMRF at 3-week intervals with a follow-up period of 3 months after treatment. Clinical improvement was evaluated using the Fitzpatrick Wrinkle Classification System (FWCS) and subjective satisfaction on a visual analog scale (VAS). The FWCS scores demonstrated significant improvement in periorbital wrinkles after treatment (P < 0.001). A satisfaction VAS score of more than 5, indicating high satisfaction, was obtained from 10 of 11 patients (91%) 3 months after treatment, and the mean satisfaction VAS score (n = 11) was 6.7. Patients undergoing treatment reported minimal pain, and neither long-lasting side-effects nor significant downtime was noted. This clinical study suggests that FMRF is a safe and tolerable method for successful treatment of periorbital wrinkles.
