Radiofrequency Devices
Radiofrequency devices use electromagnetic waves that generate heat in the vaginal tissue to stimulate collagen contraction, neocollagenesis, angiogenesis, and growth factor infiltration to restore the elasticity and moisture of the vaginal mucosa.11 Temperatures of 40° to 45°C induce collagen production by fibroblasts, which leads to soft-tissue tightening. Temperatures exceeding 47°C have been associated with burns and pain following treatment, although vaginal tissue can tolerate temperatures up to 50°C without sustaining thermal burns. Radiofrequency vulvovaginal restoration treatments typically last 15 to 30 minutes and require no anesthesia. Typically, downtime is minimal, and it is recommended that patients resume normal activity following treatment.
