I-Arbutin iyinhlanganisela yemvelo etholakala ezitshalweni ezahlukene, ikakhulukazi esitshalweni se-bearberry (Arctostaphylos uva-ursi), ama-cranberry, ama-blueberry, namapheya. Iyingxenye yesigaba samakhemikhali aziwa ngokuthi ama-glycosides. Izinhlobo ezimbili eziyinhloko ze-arbutin yi-alpha-arbutin kanye ne-beta-arbutin.
I-Arbutin yaziwa ngezakhiwo zayo zokukhanyisa isikhumba, njengoba ivimbela umsebenzi we-tyrosinase, i-enzyme ehilelekile ekukhiqizweni kwe-melanin. I-Melanin iyi-pigment ebangela umbala wesikhumba, izinwele namehlo. Ngokuvimbela i-tyrosinase, i-arbutin isiza ukunciphisa ukukhiqizwa kwe-melanin, okuholela esikhumbeni esikhanyayo.
Ngenxa yemiphumela yayo yokukhanyisa isikhumba, i-arbutin iyisithako esivamile emikhiqizweni yezimonyo nokunakekelwa kwesikhumba. Ivame ukusetshenziswa ekwakhiweni okuklanyelwe ukubhekana nezinkinga ezifana nokwanda kombala, amabala amnyama, kanye nethoni yesikhumba engalingani. Ibhekwa njengendlela elula kunezinye izinto ezikhanyisa isikhumba, njenge-hydroquinone, engaba lukhuni kakhulu esikhumbeni.
Kubalulekile ukuqaphela ukuthi nakuba i-arbutin ngokuvamile ibhekwa njengephephile ukusetshenziswa endaweni yokwelashwa, abantu abanesikhumba esibucayi noma ukungezwani komzimba kufanele baqaphele futhi benze ukuhlolwa kwe-patch ngaphambi kokusebenzisa imikhiqizo equkethe i-arbutin. Njenganoma yisiphi isithako sokunakekelwa kwesikhumba, kuyalulekwa ukubonisana nodokotela wesikhumba noma uchwepheshe wezempilo ukuze uthole iseluleko esiqondene nawe.
