Bei Jing Hop Leading-edge Laser Co., ltd LED Light L3 L6 L9 1. Theory of operating Blue light: Destroy the living condition of bacterium and kill them by human cells, The visible blue light can be perfectly absorbed by acne bacillus ,and the metabolism of bacillus will generate a mass of singlet oxygen which is harmful to the acne bacillus so as to kill them and eliminate acne ,photo-chemical reaction also accelerates the collagen fiber generation ,Red light: the red light can accelerate the growth of collagen fiber by photochemical biology activity ,the red light acts on chodriosome in dermis layer to generate more power which speeds up the synthesis of DNA,RNA,and a lot of collagen and fiber is produced and accelerate the elimination of waste or dead cell ,then to alleviate the symptom of aging skin ,large pore ,find wrinkle ,muddy complexion, mixture light: combination of the blue and red light ,alleviate serious acne and oily skin using a scientific process that applies both blue and red light ,the treatment period is similar to red light around 15 to20 minutes per time . 2. The scope of treatment The reaction of LED is driven by near-infrared ,ultraviolet ,or visible light ,this new technology is systemic administration of a photosensitiser ,which are excited by Bei Jing Hop Leading-edge Laser Co., ltd photons with chemical and biologic processes ,The photodynamic therapy (PDT) can treat a vast number of skin conditions successfully and has been proven to restore youth. LED therapy is preferentially taken up by tissues of strong mitotic activity and pathological stroma ,photosentisers develop no spontaneous toxicity ,they must be excited by photons to produce cytotoxic free radicals ,such as singlet oxygen and superoxide radicals ,these radicals selectively destroy the tumor cells having strong mitotic activities 3.
