Maziko ongoyerekeza a laser chithandizo cha khungu la pigmentation ndi kukongola kwa laser ndi chiphunzitso cha "selective photothermolysis" chomwe Dr. Anderson RR.ndi Parrish JA.ku United States mu 1983.
Kusankhidwa kwa photothermolysis ndiko kuyamwa kwapadera kwa mphamvu ya laser ndi zigawo zina za minofu, ndipo kutentha komwe kumapangidwa ndi zotsatira za kutentha kumawononga zigawo izi.
Chitetezo cha mthupi komanso kagayidwe kachakudya kamatha kuyamwa ndikuchotsa zinyalala zoonongekazi kuti tikwaniritse cholinga chochiza matenda amtundu.Nthawi yomweyo amatulutsa mphamvu ya laser kuti aphwanye bwino chromophore ya minofu yodwala.
Gawo la (epidermal) chromophore limagawika ndikutuluka ku epidermis.Mbali ya chromophore (pansi pa epidermis) imathyoledwa kukhala tinthu ting'onoting'ono tomwe titha kuzunguliridwa ndi macrophages.
Pambuyo pa chimbudzi cha phagocyte, pamapeto pake amatulutsidwa kudzera mu mitsempha ya mitsempha, ndipo chromophore ya minofu yodwala imachepa pang'onopang'ono mpaka itatha, pamene minofu yozungulira sichiwonongeka.
