Subject Satisfaction of Wrinkle Reduction Following Treatment with Fractional Radiofrequency: A Prospective Study

Abstract

Background: Fractional radiofrequency (FRF) technology reduces skin laxity and treats aging-related skin disorders such as wrinkles. The objective of this study was to evaluate participant satisfaction of FRF for the treatment of facial wrinkles. Methods: A total of 25 male and female patients (average age 60.5 years) were enrolled in this prospective, single center study. Patients received 3 FRF treatments at 3- to 5-week intervals on both sides of the face, using 80-pin (up to 124 millijoule/pin) or the 160-pin tip (up to 62 millijoule/pin) applicator. Follow-up visits were conducted at 6 and 12 weeks after the last treatment. Participant satisfaction was evaluated by individual self-assessment of wrinkle reduction and a patient satisfaction questionnaire. Pain, tolerability, and safety were monitored throughout. Results: The individual satisfaction was high with participants giving an average satisfaction score of 2.8 ("satisfied") out of 4. Pain was rated "mild" with an average of 4.0 on a 10-point Visual Analog Scale (VAS). Tolerability was rated 3.3 out of 4.0, correlating to "very tolerable". Ninety percent (90%) of subjects reported a mild or moderate improvement in their treatment area at 12-week follow-up. Conclusion: This study demonstrates that under the FRF pre-sets used, patients are satisfied with results of FRF modality for improvement of their wrinkles. No unanticipated side effects were observed. Treatment was tolerable, and individuals had high levels of satisfaction and tolerability with the results at last follow-up.
