Ukuhlelwa kwesikhumba sikaFitzpatrick kukuhlelwa kombala wesikhumba kwiintlobo ze-I-VI ngokweempawu zempendulo yokutsha okanye ukutshiswa lilanga emva kokuvezwa lilanga:
Uhlobo I: Mhlophe; umhle kakhulu; iinwele ezibomvu okanye ezimthubi; amehlo aluhlaza okwesibhakabhaka; amabala
Uhlobo II: Mhlophe; mhlophe; iinwele ezibomvu okanye ezimhlophe, luhlaza okwesibhakabhaka, i-hazel, okanye amehlo aluhlaza
Uhlobo lwesithathu: Ikhrimu emhlophe; inombala omhlophe okanye okhanyayo; ixhaphake kakhulu
Uhlobo lwesine: Umdaka; abantu abaqhelekileyo baseMeditera, iintlobo zolusu lwaseIndiya/lwaseAsia
Uhlobo V: Iintlobo zolusu ezimdaka ngombala omnyama, ezikummandla wasempuma
Uhlobo VI: Mnyama
Ngokwesiqhelo kukholelwa ukuba abantu baseYurophu naseMelika banomlinganiselo omncinci we-melanin kumaleko osisiseko wolusu, kwaye ulusu lulolweentlobo I kunye ne-II; ulusu olumthubi kuMzantsi-mpuma we-Asia luhlobo lwe-III, IV, kwaye umxholo we-melanin kumaleko osisiseko wolusu uphakathi; ulusu olumnyama-mdaka lwase-Afrika luhlobo lwe-V, VI, kwaye umxholo we-melanin kumaleko osisiseko wolusu uphezulu kakhulu.
Kwi-laser yolusu kunye nonyango lwe-photon, i-chromophore ekujoliswe kuyo yi-melanin, kwaye umatshini kunye neeparamitha zonyango kufuneka zikhethwe ngokohlobo lolusu.
Uhlobo lolusu lusisiseko esibalulekileyo sethiyori kwi-algorithm yeisihlalutyi solusuNgokwethiyori, abantu abanemibala eyahlukeneyo yolusu kufuneka basebenzise iindlela ezahlukeneyo zokuchonga xa bebona ingxaki yokutshintsha umbala, nto leyo enokuphelisa umahluko kwiziphumo ezibangelwa yimibala eyahlukeneyo yolusu kangangoko kunokwenzeka.
Nangona kunjalo, okwangokuumatshini wokuhlaziya ulusu lobusoEzi marike zineengxaki ezithile zobugcisa zokuchonga ulusu olumnyama nolumdaka, kuba ukukhanya kwe-UV okusetyenziselwa ukubona umbala phantse kutsalwa ngokupheleleyo yi-eumelanin kumphezulu wolusu. Ngaphandle kokubonakalisa,isihlalutyi solusuayinakubamba amaza okukhanya abonakalayo, ngoko ke ayinakubona ukutshintsha kombala wolusu.
