Treatment of periorbital aging with negative pressure fractional microneedle radiofrequency: A self‐controlled clinical trial

Abstract

BackgroundSeveral treatment modalities are used for the treatment of periorbital rejuvenation with variable results. Recent studies showed that fractional radiofrequency may be an effective treatment modality for periorbital aging. This study aims to determine the efficacy and safety of negative pressure fractional microneedle radiofrequency (NPFMR) as a treatment for periorbital aging.MethodsTwenty‐five patients with periorbital aging were involved in this study. They were treated two times with an interval of 1 month. The patients were evaluated before treatment and 1, 3, and 6 months after the final treatment.ResultsThe research findings suggest that periorbital wrinkles of the patients were significantly improved by VISIA system (p < 0.05). Physiological indicators detected by MPA10 system showed that compared with before treatment, the hydration increased (p < 0.05) and trans epidermal water loss (TEWL) decreased (p < 0.05) at 3 and 6 months after treatment. The glossiness increased at 1 month after treatment compared to pre‐treatment (p < 0.05) and returned to the baseline level at 3 and 6 months after treatment. There was no significant change in melanin content (p > 0.05). Periorbital dermal thickness of the patients significantly increased at 1, 3, and 6 months after treatment according to skin ultrasound (p < 0.05). A periorbital skin biopsy revealed that the collagen fibers in the dermis were significantly thicker and more orderly after treatment, and the expression of type I collagen fibers and elastic fibers was increased compared with that before treatment. One patient developed post‐inflammatory hyperpigmentation (PIH) at 1 month after the first treatment, which improved after active treatment. No other adverse reactions were observed.ConclusionsNPMFR could be an effective and safe treatment modality for the treatment of periorbital aging.
