Working Principle : The main principle of 808nm diode laser hair removal system is selective photothermolysis (SPTL). 808nm laser emits the gold wavelength of light, 808nm to penetrate into hair follicle. Using the theory of selective optical absorption, laser can be preferentially absorbed by the melanin of the hair. And then the hair shaft and hair follicle are heated rapidly in order to destroy the oxygen-supply organization and around the hair follicle. So that the hair follicles is to stop growing, damage hair follicle degeneration and atrophy to achieve permanent hair removal. Non- Channel Diode Laser Working Method: 808nm diode laser system features with SHR In-motion and stamping method for hair removal. SHR works by gradually heating the dermis to a temperature that effectively damages the hair follicles and prevents re-growth, while avoiding injury to the surrounding tissue. The sweeping In-Motion technique of moving the applicator repeatedly over the treatment area ensures full coverage while sapphire cools the skin surface - preventing superficial burns and allowing for virtually painless, yet highly effective hair removal. no side effects in dark skinned patients. Our Permanent Hair Removal Machine utilizes upgraded technology Non-Channel instead of micro-channel or macro-channel handle .Because of special chips arrangement non-channel handle can take up the water temperature 55ºC, while both micro and macro channels can only take maximum 35ºC.What's more, Non-channel handle support the maximum current 130 A. Micro-channel and macro-channel can only take 60Aand 40Arespectively.For that reason the upgraded diode laser ensures longer working hours than other technologies on the market., and you never will have to suffer from the handle-burning problems again and again.
