I-UV phototherapyiwukwelashwa kokukhanya kwe-ultraviolet okungu-311 ~ 313nm. Futhi kwaziwa ngokuthi ukwelapha ngemisebe ye-spectrum emincane ye-ultraviolet (Ukwelashwa kwe-NB UVB).Ingxenye encane ye-UVB: ubude begagasi obungu-311 ~ 313nm ingafinyelela ungqimba lwe-epidermal lwesikhumba noma lapho kuhlangana khona i-epidermis yangempela, futhi ukujula kokungena akujulile, kodwa kusebenza nje kumaseli okuhlosiwe njengama-melanocyte, futhi inomphumela wokwelapha.
Izivivinyo zemitholampilo zibonise ukuthi ububanzi be-wavelength obungu-311-312 nm obukhishwa yi-311 ye-spectrum ewumngcingo ye-UVB buthathwa njengokukhanya okuphephile nokusebenza kakhulu. Inezinzuzo zokusebenza kahle kanye nemiphumela emibi emincane ye-psoriasis, i-vitiligo nezinye izifo zesikhumba ezingapheli.
Kodwa-ke, kungcono kakhulu ukulandela iseluleko sikadokotela noma imiyalelo lapho usebenzisa ithuluzi le-ultraviolet phototherapy, ngoba ukusetshenziswa ngokweqile kwe-ultraviolet ithuluzi le-phototherapy kuzovela ukusha okuncane, okubonakaliswa njengesikhumba esibomvu, ukuvutha, ukuxebuka kanye nezinye izimpawu zokusha okuncane.
Okwesibili, imisebe ye-ultraviolet izophinde ilimaze i-retina ngokusebenzisa i-cornea, okuholela ekulimaleni kwe-retinal cell, ngakho-ke abantu noma izilwane ezichayeke emisebeni ye-ultraviolet isikhathi eside babefaneleka ukugqoka izingubo zokuzivikela nezinye izinto zokusebenza, bafake izibuko zelanga ezivikelayo.
