Treatment of periorbital wrinkles with a novel fractional radiofrequency microneedle system in dark-skinned patients.

BACKGROUND: 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.

OBJECTIVE: 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.

MATERIALS AND METHODS: 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.

RESULTS: 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.

CONCLUSION: The system may be an effective and safe treatment option for periorbital wrinkles in dark-skinned Korean patients.
