Intshayelelo
I-β-Arbutin isetyenziswa njengesithako esimhlophe sokulawula ukuveliswa kwee-melanin pigments, zizinto ezibangela ukujika kombala kunye namabala.
Yaziwa njengento equlethwe kwimifuno ericaceous ebizwa ngokuba yi-bearberry leaf.Ukutshintsha kombala kunye namabala kwenzeka ngenxa yeoksijini esebenzayo eveliswa eluswini ngokuvezwa kwi-UV ekukhanyeni kwelanga, uxinzelelo, ungcoliseko lomoya, njl.njl., eyenza i-tyrosinase isebenze kwaye i-enzyme esebenzayo ikhuthaza ukuguqulwa kwe-tyrosine kwi-melanocytes (iiseli ze-pigment) kwi-melanin pigments.I-β-Arbutin kuthiwa ibonisa iziphumo ezimhlophe ngokunciphisa imveliso ye-melanin pigments ngokusebenza ngokuthe ngqo kwi-tyrosinase kwi-melanocytes.
