Abstract

Abstract: Background: Facial wrinkles and sagging are the most visible signs of aging and can cause profound distress. Microneedle fractional radiofrequency (MFR) is a minimally invasive procedure, which utilizes both microneedling and radiofrequency energy to rejuvenate the skin. Objective: To describe the safety and efficacy of a temperature‐controlled MFR device on facial fine lines and laxity. Patients and Methods: A retrospective chart & histology review was performed on individuals who received bipolar MFR for facial rejuvenation. A total of 15 Koreans with a median age of 46 years were included. All participants underwent a single treatment session. The results were assessed objectively using serial photography and subjectively based on the participants' satisfaction scores. Histologic changes before, immediately after MFR and at 4 months follow‐up was examined. Complications were also recorded. Results: Partially denatured collagen fibers and dermal shrinkage was observed immediately after MFR whereas an increase in elastin and collagen was noted at 4 months follow‐up. 86.7% of recipients considered the results satisfactory. Consensus ratings by two independent dermatologists on the objective outcomes at 4‐month follow‐up were very much improved (53.3%), much improved (26.7%) and improved (20%). Treatment was well tolerated and did not cause any significant long‐lasting discomfort. Conclusion: Temperature‐controlled bipolar MFR is a minimally invasive treatment option to consider for facial fine lines and laxity via neo‐collagenesis and neo‐elastogenesis. The procedure was safe and clinically effective.
