Trademarked by Silk'n, the Glide Unisex works by using HPL, the home version of the well-known IPL hair removal technology by Silk'n. Clinically proven to remove hair from its follicles using pulses of light, the light energy is absorbed in the hair shaft. This energy is transformed into heat, which disables the hair follicle, in turn reducing its ability to grow. The tissue around the hair follicle is kept at a normal temperature whilst the hair follicle absorbs the light energy. After each treatment, the hair growth is reduced and by following the recommended treatment plan for the area you want to treat, you can enjoy up to 92% permanent hair reduction. Silk'n HPL technology works on a wide range of skin tones and hair colours, including darker skin tones which is not typical of many light pulsed devices. You can also use the Silk'n Glide Unisex after sunbathing on setting 1.
