**8nm waelength laser can penetrate the epidermis to reach the deep hair follicle tissue effectively, by special setting the pulse duration guarantee the target tissue to generate sufficient thermal damage  and the surrounding tissue is almost unaffected:the right amount of energy density guarantee to provide sufficiently strong enough output energy in the appropriate time to  damage the target tissue  and normal tissue is almost equally affected; appropriate measures to protect the epidermis guarantee to damage the target  tissue enoug, while the epidermis is almost unaffected, thus protect the safety of the treatment. Hair follicle tissue absorbs the laser energy and heat then being heated to *0 degree,the hair follicle and growth of stem cells lose the growth activity, so as to achieve the purpose of permanent hair removal.
