Ulusu oluqhelekileyo lunamandla okufunxa ukukhanya ukuze lukhusele amalungu kunye nezicubu zomzimba ekonakalisweni kokukhanya. Amandla okukhanya ukungena kwizicubu zomntu anxulumene kakhulu nobude bawo kunye nolwakhiwo lwezicubu zesikhumba. Ngokubanzi, okukhona ubude bawo bufutshane, kokukhona ukungena okuncinci eluswini. Izicubu zesikhumba zifunxa ukukhanya ngokukhetha okucacileyo. Umzekelo, ii-keratinocytes kwi-stratum corneum zinokufunxa inani elikhulu lemitha ye-ultraviolet yamaza amafutshane (ubude bawo buyi-180 ~ 280nm), kwaye iiseli ze-spinous kumaleko we-spinous kunye ne-melanocytes kumaleko we-basal zifunxa imisebe ye-ultraviolet yamaza amade (ubude bawo buyi-320 nm ~ 400nm). Izicubu zesikhumba zifunxa ubude bawo obuhlukeneyo bokukhanya ngokwahlukileyo, kwaye uninzi lwemitha ye-ultraviolet ifunxwa yi-epidermis. Njengoko ubude bawo bukhula, izinga lokungena kokukhanya nalo liyatshintsha. Imisebe ye-infrared kufutshane nomatshini wokukhanya obomvu ingena kwiingqimba ezinzulu zesikhumba, kodwa ifunxwa lusu. I-infrared yamaza amade (ubude bamaza yi-15 ~ 400μm) ayingeni kakuhle kakhulu, kwaye uninzi lwayo lufunxwa yi-epidermis.
Oku kungasentla sisiseko sethiyori sokubaisihlalutyi solusuingasetyenziselwa ukubona iingxaki zombala wesikhumba onzulu.isihlalutyi solusuisebenzisa ii-spectra ezahlukeneyo (i-RGB, ukukhanya okunqamlezileyo, ukukhanya okujikelezileyo okulinganayo, ukukhanya kwe-UV kunye nokukhanya kukaWood) ukwenza ubude obuhlukeneyo bobude ukuze kufunyanwe iingxaki zesikhumba ukusuka kumphezulu ukuya kumaleko onzulu, ngoko ke imibimbi, imithambo yesigcawu, iimbobo ezinkulu, amabala omphezulu, amabala anzulu, umbala, umbala, ukudumba, ii-porphyrins kunye nezinye iingxaki zesikhumba zinokufunyanwa yi-skin analyzer.
