Treatment of Periorbital Wrinkles With a Novel Fractional Radiofrequency Microneedle System in Dark-Skinned Patients

Periorbital wrinkles as a result of photoaging are a frequent cosmetic concern. Recently, the fractional radiofrequency microneedle system was introduced as a new device for facial rejuvenation, and it has received much recognition for its unique "deep dermal heating with epidermal sparing" feature.The purpose of this study was to examine the clinical efficacy and safety of the system for the treatment of periorbital wrinkles in Korean patients.Twenty Korean patients (Fitzpatrick skin Type IV-V) with varying degrees of periorbital wrinkles were enrolled in this study. The patients were treated 3 times at 4-week intervals with the system. Changes in periorbital wrinkling were evaluated by 2 independent experts with digital images of the subjects' faces using a 5-point Wrinkle Assessment Scale. At the end of the study, the patients rated their satisfaction with the overall treatment outcome on a numerical scale.All patients completed the treatment regimen and were satisfied with the treatment. Most patients improved according to clinical and photographic assessments performed 6 months after the treatment. Two patients (10%) reported mild hyperpigmentation.The system may be an effective and safe treatment option for periorbital wrinkles in dark-skinned Korean patients.
