Usually 4 - 6 treatments at 6 - 12 week intervals are needed. The number varies depending on the colour of the hair, the colour of the skin, the area being treated and your adherence to the appropriate schedule of treatments for that specific area. Skinpossible offers a 6 Treatment Series for the normal price of only 5 treatments. In the event fewer than 5 are needed, any balance that remains on your account can be applied to any other treatment or product we offer.
