Isingeniso
I-β-Arbutin isetshenziswa njengesithako esimhlophe sokulawula ukukhiqizwa kwemibala ye-melanin, okuyizinto ezidala ukushintsha kombala kanye nama-freckles.
Yaziwa njengento equkethwe kumakhambi ericaceous okuthiwa i-bearberry leaf.Ukushintsha umbala kanye namafreckles kwenzeka ngenxa yomoya-mpilo osebenzayo okhiqizwa esikhumbeni ngokuchayeka ku-UV ekukhanyeni kwelanga, ingcindezi, ukungcoliswa komoya, njll., okwenza kusebenze i-tyrosinase kanye ne-enzyme ecushiwe ikhuthaza ukuguqulwa kwe-tyrosine kuma-melanocytes (amangqamuzana e-pigment) ku-melanin pigments.I-β-Arbutin kuthiwa ikhombisa imiphumela emhlophe ngokunciphisa ukukhiqizwa kwemibala ye-melanin ngokusebenza ngokuqondile ku-tyrosinase kuma-melanocyte.
