The biggest question that you’ll likely have is about the procedure itself, including what it is and how it works. This is the first treatment of its kind approved by the FDA that uses radio-frequency. It uses a handpiece called an applicator, which is only 0.5-inches wide. The active tip on the end uses that frequency to gently tighten the skin on your vagina without causing any discomfort. More than 130,000 women sought this treatment since it became available in 2016.
