The theory of selective photothermy and decomposition is an extent of traditional photothermy.Integratingmerits of both invasive and non-invasive treatment,cO2 fractional laser device has fast and clear curative effects,minor side effects and short recovery time.The treatment with CO2 laser refers to acting on skin with micro-holes;three areas including thermal desquamation thermal coagulation and thermal effects are formed.Aseries of biochemical reactions will occur to skin and stimulate skin in self-healingSkin firming.
tendering and colored spotremovaleffect can be achieved.Since the fractional laser treatment only covers part of skin tissues and new macro-holes will not be overlapped.Thus,part of normal skin will be reserved,which quickens recover.
