Working Principle : The main principle of Professional 808nm Diode Laser 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. Working Method: 808nm diode laser 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.
