Features: Gentle and effective even on the most sensitive areas of the body, this light-based system uses IPL technology derived from professional salons to deliver up to 75% hair reduction after only four treatments or two months The light produces heat, which is transferred to the hair follicle and triggers it to go into a resting phase. As a result, the hair sheds naturally and regrowth is inhibited Professional grade IPL targets the pigment in your hair and permanently disables the hair follicle`s ability to regrow hair.
