Lobu buchwepheshe baziwa ngokuthi yi-Fractional Photothermolysis theory (ukukhanya kwamachashazi kanye nokubola kokushisa), i-laser eyi-far-infrared engu-10.6μm izomaka ngokulinganayo ngezimbobo ezincane, bese idala uchungechunge lokusabela kwamakhemikhali esikhumbeni, ngaleyo ndlela ifinyelele imiphumela yesikhumba. ukuphakamisa nokufaka kabusha, i-pigments nokususwa kwezibazi, njll, ekugcineni vumela isikhumba sibuyele sibe sincane futhi.
