Effectiveness and safety of nonablative Fractional unipolar radiofrequency for periorbital wrinkles

초록

Background: Non-ablative fractional laser and radiofrequency are popular for treating periorbital fine wrinkles owing to no downtime and low risk of side effects. Among the various techniques, noninvasive fractional unipolar radiofrequency (RF) device has used to be an treatment option for various types of rhytids. Objective: The purpose of this study was to evaluate the efficacy and safety of a fractional unipolar RF device on periorbital wrinkle. Materials and Methods: Ten patients who were treated for periorbital wrinkles using a fractional unipolar RF device. Fractional unipolar RF was applied to the periorbital area every 2-3 weeks for a total of 5 sessions. No topical anesthetic was applied during the procedure. Efficacy was assessed using the Global Aesthetic Improvement Scale(GAIS) and Glogau classification. Pain scores and adverse events were checked. Results: Eight female and two male patients with a mean age of 48.6 years, age range 40∼60years were included in this study. Five patients showed GAIS scoring 1 (very much improved), the other five patients showed GAIS scoring 2 (improved). Among the patients, 90% reported a pain score of 1, while 10% reported pain scores of 2. No adverse events, such as burn, hyperpigmentation, were observed. Conclusion: We demonstrated the efficacy and safety of the fractional unipolar RF device in treating periorbital wrinkles. Our study suggests that offers improvement in periorbital fine wrinkle in the Asian population.
