Isikhumba esivamile sinekhono lokumunca ukukhanya ukuze sivikele izitho nezicubu emzimbeni ekulimaleni kokukhanya. Amandla okukhanya ukungena ezicutshini zomuntu ahlobene kakhulu nobude bawo kanye nesakhiwo sezicubu zesikhumba. Ngokuvamile, uma ubude bawo bufushane, kulapho ukungena okujulile esikhumbeni. Izicubu zesikhumba zimunca ukukhanya ngokukhetha okusobala. Isibonelo, ama-keratinocyte ku-stratum corneum angamunca inani elikhulu lemisebe ye-ultraviolet yamaza amafushane (ubude bawo bungu-180 ~ 280nm), kanti amaseli e-spinous kungqimba lwe-spinous kanye nama-melanocyte kungqimba oluyisisekelo amunca imisebe ye-ultraviolet yamaza amade (ubude bawo bungu-320 nm ~ 400nm). Izicubu zesikhumba zimunca ubude bamaza obuhlukene bokukhanya ngendlela ehlukile, futhi iningi lemisebe ye-ultraviolet limuncwa yi-epidermis. Njengoba ubude bamaza bukhula, izinga lokungena kokukhanya nalo liyashintsha. Imisebe ye-infrared eduze komshini wokukhanya obomvu ingena ezingqimbeni ezijulile zesikhumba, kodwa imuncwa yisikhumba. I-infrared yamagagasi amade (ubude bamagagasi bungu-15 ~ 400μm) ayingeni kahle kakhulu, futhi iningi layo limuncwa yi-epidermis.
Lokhu okungenhla kuyisisekelo semfundiso yokuthiisihlaziyi sesikhumbaingasetshenziswa ukuthola izinkinga zokushintsha umbala wesikhumba ngokujulile.isihlaziyi sesikhumbaIsebenzisa ama-spectra ahlukene (i-RGB, ukukhanya okuphambeneyo, ukukhanya okuphambeneyo, ukukhanya kwe-UV kanye nokukhanya kwe-Wood) ukudala ubude obuhlukene bamaza ukuze kutholakale izinkinga zesikhumba kusukela ebusweni kuya ongqimbeni olujulile, ngakho-ke imibimbi, imithambo yesicabucabu, ama-pores amakhulu, amabala ebusweni, amabala ajulile, umbala, umbala, ukuvuvukala, ama-porphyrins nezinye izinkinga zesikhumba konke kungatholakala nge-skin analyzer.
