Applications For any unwanted hairs on areas of face, arms, armpits, chest, back, bikini, legs and etc. (including light, blond and thin hairs) Working Principle Diode laser hair removal technology is based on the selective dynamics of light and heat. The laser goes through the skin surface to reach the root of hair follicles; light can be absorbed and converted into heat damaged hair follicle tissue, so that hair loss regeneration without injury surrounding tissue. Slight pain, easy operation, the safe, technology for permanent hair removal now. It is performed using gold standard 808nm or Triple-wavelength(755nm+808nm+1064nm) diode laser technology, with energy penetrates deep into the dermis with high average power and a rapid 10 pulse-per-second repetition rate to heat the hair shaft and hair follicle, rather than destroy the oxygen organization around hair follicle. Meanwhile, contacting surface cooling technology applied on the Sapphire tip can eliminate the heat effect attributed to optical energy, greatly improving both the treatment performance and safety.
