Saldhigga aragtida ee daaweynta laysarka ee midabaynta maqaarka iyo quruxda laysarka waa aragtida "photothermolysis xulashada" oo uu soo jeediyay Dr. Anderson RR.iyo Parrish JA.ee dalka Maraykanka 1983kii.
Photothermolysis xulashada waa nuugista tamarta laysarka ee qaybo gaar ah oo unugyo gaar ah, iyo kulaylka ka dhasha saamaynta kulaylku wuxuu burburiyaa qaybahan unugyada gaarka ah.
Hababka difaaca jirka iyo dheef-shiid kiimikaadka ayaa nuugi kara oo baabi'in kara burburka nudaha dhaawacan si loo gaaro yoolka lagu daweeyo cudurrada midabka leh.Isla markiiba sii daaya tamarta laysarka si ay si hufan u burburiso koromophore-ka unugyada buka.
Qayb ka mid ah koromophore-ka (epidermal) ayaa kala go'ay oo laga soo saaray xuubka sare.Qayb ka mid ah chromophore-ka (ee epidermis hoosteeda) ayaa u jajaban qaybo yaryar oo ay ku dabooli karaan macrophages.
Ka dib dheefshiidka phagocyte, ugu dambeyntii waxaa laga soo saaraa wareegga lymfatic, koromophore-ka unugyada buka ayaa si tartiib tartiib ah u yaraan doona ilaa uu ka ba'o, halka unugyada caadiga ah ee ku hareeraysan aysan dhaawacmin.
