Femiwave sessions can be repeated every 7 to 10 days for the initial series. Your current health, age, medical conditions, and hormonal balance will all play a role in the longevity of your results. For many individuals the results can last as long as 2 years. Because the treatment is all natural and without any known risks, it is safe and recommended to get periodic maintenance treatments to ensure long lasting results. For many women a good plan would be to expect to do a maintenance session once or twice a year. This will vary of course depending on the severity of initial symptoms, and individual variation in tissue response.
