Principle :

808nm wavelength laser can penetrate skin epidermis to reach the deep hair follicle tissue, through specially set pulse duration to protect target tissue to produce enough heat damage, the surrounding tissue almost unaffected; Adequate energy density guarantees sufficient energy output to damage the target tissue within the appropriate time, and the normal tissue is also almost unaffected; the appropriate skin protection measures protect the target tissue enough damage, and the epidermis is almost unaffected, thus ensuring the safety of treatment.   Hair follicle tissue and after absorbing the energy and heat of the laser is heated to about 50 degrees, hair follicle and growth stem cells that lose their growth activity, so as to achieve the purpose of permanent hair removal.
