Amakhulupirira kuti anthu a ku Ulaya ndi ku America ali ndi melanin yochepa pakhungu, ndipo khungu ndi la mtundu wa I ndi II; khungu lachikasu kum'mwera chakum'mawa kwa Asia ndi mtundu wa III, IV, ndipo zomwe zili mu melanin mu basal wosanjikiza wa khungu ndizochepa; Khungu lakuda lakuda ku Africa ndi mtundu wa V, VI, ndipo zomwe zili mu melanin m'munsi mwa khungu ndizokwera kwambiri.

Pochiza khungu la laser ndi photon, chromophore chandamale ndi melanin, ndipo makina ndi zida zamankhwala ziyenera kusankhidwa molingana ndi mtundu wa khungu.

Khungu mtundu ndi yofunika chiphunzitso maziko a aligorivimu wakhungu analyzer. Mwachidziwitso, anthu omwe ali ndi mitundu yosiyanasiyana ya khungu ayenera kugwiritsa ntchito njira zosiyana siyana pozindikira vuto la mtundu wa pigmentation, zomwe zingathe kuthetsa kusiyana kwa zotsatira zomwe zimayambitsidwa ndi mitundu yosiyanasiyana ya khungu momwe zingathere.

Komabe, panopamakina osanthula khungu la nkhopepa msika ndi zina luso mavuto kudziwika khungu lakuda ndi loderapo, chifukwa UV kuwala ntchito kudziwa pigmentation pafupifupi kwathunthu odzipereka ndi eumelanin pa khungu pamwamba. Popanda kusinkhasinkha,khungu analyzersilingagwire mafunde owala, choncho silingazindikire kusinthika kwa khungu.
