Imisebe ye-Ultraviolet (UV) iyingxenye ye-electromagnetic (ukukhanya) spectrum efinyelela emhlabeni isuka elangeni. Inama-wavelength amafushane kunokukhanya okubonakalayo, okwenza ingabonakali emehlweni. I-Ultraviolet A (UVA) iyi-wave ende ye-UV ray ebangela ukulimala kwesikhumba okuhlala isikhathi eside, ukuguga kwesikhumba, futhi engabangela umdlavuza wesikhumba. I-Ultraviolet B (UVB) iyi-wave emfushane ye-UV ray ebangela ukushiswa yilanga, ukulimala kwesikhumba, futhi engabangela umdlavuza wesikhumba.
Izikrini zelanga ziyimikhiqizo ehlanganisa izithako eziningana ezisiza ekuvimbeleni imisebe ye-ultraviolet (UV) yelanga ukuthi ingafiki esikhumbeni. Izinhlobo ezimbili zemisebe ye-ultraviolet, i-UVA ne-UVB, zilimaza isikhumba futhi zandise ingozi yakho yomdlavuza wesikhumba. Izikrini zelanga ziyahlukahluka ngekhono lazo lokuvikela ku-UVA ne-UVB.
Isikrini selanga singasiza ekuvimbeleni umdlavuza wesikhumba ngokuvikela emisebeni ye-ultraviolet eyingozi yelanga. I-American Academy of Dermatology itusa wonke umuntu ukuthi asebenzise isivikelo selanga esihlinzeka okulandelayo: Isivikelo se-Broadspectrum (sivikela emisebeni ye-UVA ne-UVB) I-Sun Protection Factor (SPF) engu-30 noma ngaphezulu.
I-Diethylhexyl Butamido Triazoneiyinhlanganisela emunca kalula imisebe ye-UVA kanye ne-UVB futhi ivame ukutholakala ku-sunscreen kanye neminye imikhiqizo yokunakekela ilanga.
Ngenxa yokuncibilika kwayo okuhle kakhulu kumafutha amaningi ezimonyo, kudingeka amazinga aphansi kuphela ukuze kufakwe izithako ezisebenzayo ezanele ukuze kufinyelelwe ama-SPF aphezulu.
Isetshenziswa ngamanani afinyelela ku-10% ․ Ihlunga imisebe ye-UVB, kanye neminye imisebe ye-UVA.
Isithambisi se-UV esibanzi sinikeza i-Factor yokuvikela ilanga enhle kakhulu. Sisebenzisana kahle nezinye izihlungi ze-UV. Ama-creams, ama-lotion, ama-seum, ama-deodorants, izinsipho zobuhle, ama-sunscreen asebusuku. Imikhiqizo yokwenza/ izimonyo zombala. Incibilika esigabeni samafutha se-emulsion. Isithambisi se-UV esibanzi ngokwemvelo. Ukungathandi amanzi kanye nokuncibilika kwawo emafutheni okwenziwe lula ukuze kusetshenziswe ama-formula amelana namanzi.
I-Diethylhexyl Butamido Triazoneiyinhlanganisela ephilayo esekelwe ku-triazine emunca kalula imisebe ye-UVA kanye ne-UVB. I-Iscotrizinol ivame ukutholakala ku-sunscreen kanye neminye imikhiqizo yokunakekela ilanga.
