Usefulness of Monopolar Thermal Radiofrequency Treatment for Periorbital Wrinkles.

BACKGROUND: Over the past 10 years, monopolar radiofrequency (MRF) technology has been widely used by dermatologists as a valuable modality to effectively tighten and rejuvenate photoaged skin. It also has the benefit of a short recovery time. OBJECTIVE: Using an objective parameter, this study aimed to assess the efficacy and safety of MRF, which is the basic modality of radiofrequency technologies, for treatment of periorbital wrinkles in Korean patients. METHODS: We enrolled 70 middle-aged female patients with periorbital wrinkles for this study. Each patient underwent triple sessions of MRF treatment in the periorbital region, separated by 2-week intervals. Clinical photographs were obtained, and the areas of wrinkles were measured using a Robo Skin Analyzer CS50 (Inforward Inc., Japan) at baseline and 4 weeks after the final treatment session. RESULTS: Significant reduction in the mean area of periorbital wrinkles was detected at 1-month follow-up (80.64±28.96 mm2) compared to baseline (95.08±31.93 mm2). The improvement ratio of the wrinkle area was 15.19%. Pain during procedure seemed to be tolerable without any local anesthesia for all patients. Transient mild erythema was the only side effect reported during the study. CONCLUSION: In conclusion, MRF could still be an attractive modality for Korean patients with periorbital wrinkles if the treatment is conducted repeatedly with sufficient energy and proper intervals.

Treatment of periorbital wrinkles using multipolar fractional radiofrequency in Korean patients.

A limited number of studies have evaluated the efficacy and safety of electrode pin fractional radiofrequency (FRF) for periorbital wrinkle treatment in Asian patients, but none have measured noninvasive methodological objective parameters such as periorbital wrinkle area. This study aimed to investigate the efficacy and safety of electrode pin multipolar FRF for the improvement of periorbital wrinkles in Korean patients by using a noninvasive methodological objective parameter. Seventy female subjects with periorbital wrinkles (age range, 40-60 years) participated in this study. Each patient underwent three sessions of FRF treatment to the periorbital region separated by 2-week intervals. The area of periorbital wrinkles was analyzed by using a Robo Skin Analyzer CS50 at 4 weeks after the final treatment session. Periorbital wrinkle area was significantly decreased at 1-month follow-up (75.77 ± 29.46 mm2) compared to baseline (94.74 ± 31.62 mm2). The improvement ratio of periorbital wrinkle area was 20.02 %. Side effects were limited to transient mild erythema, swelling, and crusts. Pain was tolerable without local anesthesia. Our findings suggest that the multipolar electrode pin FRF can be an effective and safe method for reducing periorbital wrinkles in Asian patients.
