Abstract
BackgroundInfraorbital dark circles (IDC) are commonly consulted in aesthetic practice. There is not yet a multifactorial approach to facilitating their treatment.ObjectiveTo investigate the safety and efficacy of the microneedle fractional radiofrequency (MRF) system for the treatment of IDC.MethodsA prospective, split-face, evaluator-blind clinical trial was conducted to study the change in the overall appearance, color, and wrinkles in 21 female patients with mixed type IDC before and after MFR treatment.ResultsBoth patients and independent evaluators found significant improvement on the global aesthetic scales after the MFR treatment, especially on periorbital wrinkles (p=0.031). Trends in decreased melanin density in the IDC area were found, but no statistical differences were established. No side effects were observed.ConclusionMFR is a safe and effective modality for improving mixed type IDC by correcting the structural factors.
