Ukwelapha ukukhanya okubomvukanye nokushukwa kwe-UV yizindlela ezimbili zokwelapha ezihlukene ezinemiphumela ehlukile esikhumbeni.
Ukwelapha ukukhanya okubomvuisebenzisa uhla oluthile lwamaza okukhanya okungewona ama-UV, ngokuvamile aphakathi kuka-600 no-900 nm, ukuze ingene esikhunjeni futhi ikhuthaze izinqubo zokuphulukisa zemvelo zomzimba.Ilambu elibomvuisiza ukwandisa ukugeleza kwegazi, ukukhiqizwa kwe-collagen, kanye ne-cell urnover, okuholela ekuthuthukisweni kokuthungwa kwesikhumba, ithoni, kanye nempilo yonke.Ukwelashwa kokukhanya okubomvu kubhekwa njengokwelashwa okuphephile nokungaphazamisi okungalimazi isikhumba, futhi kuvame ukusetshenziselwa ukunciphisa ukubukeka kwemigqa emihle, imibimbi, izibazi, nezinduna, kanye nokukhuthaza ukuphulukiswa kwesilonda nokukhulula ubuhlungu.
Ngakolunye uhlangothi, ukushukwa kwe-UV kusebenzisa ukukhanya kwe-ultraviolet, okuwuhlobo lwemisebe engase ibe yingozi esikhumbeni ngokwedlulele.Ukuchayeka emisebeni ye-UV kungalimaza i-DNA yesikhumba, okuholela ekugugeni ngaphambi kwesikhathi, ukugcwala kwebala elibomvu, kanye nengozi eyengeziwe yomdlavuza wesikhumba.Imibhede yokushuka iwumthombo ovamile wemisebe ye-UV, futhi ukusetshenziswa kwayo kuye kwaxhunyaniswa nengozi eyengeziwe yomdlavuza wesikhumba, ikakhulukazi entsheni.
Kafushane, ngenkathiukwelapha ukukhanya okubomvufuthi ukushuka kwe-UV kokubili kuhilela ukuchayeka kokukhanya esikhumbeni, kunemiphumela ehlukene kanye nezingozi.Ukwelashwa ngokukhanya okubomvu kuyindlela yokwelapha ephephile futhi engahlaseli esiza ukukhuthaza impilo yesikhumba, kuyilapho ukushuka kwe-UV kungaba yingozi esikhumbeni futhi kuhlotshaniswa nengozi eyengeziwe yokulimala kwesikhumba nomdlavuza.
