I Theory 810nm system uses the unique laser with long pulse width 810nm 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 of and around the hair follicle. The system's unique super-cooling technology could bring about certain anesthetic effect to the epidermis with the
