Taw qhia
β-Arbutin yog siv los ua cov tshuaj pleev xim dawb rau kev tswj cov cim ntawm melanin pigments, uas yog cov khoom ua rau cov xim tsis muaj xim thiab freckles.
Nws yog lub npe hu ua ib yam khoom muaj nyob rau hauv ericaceous tshuaj ntsuab hu ua bearberry nplooj.Discoloration thiab freckles tshwm sim vim reactive oxygen tsim nyob rau hauv daim tawv nqaij los ntawm raug UV nyob rau hauv tshav ntuj, kev nyuaj siab, atmospheric pa phem, thiab lwm yam, uas activates tyrosinase thiab lub activated enzyme txhawb kev hloov ntawm tyrosine nyob rau hauv melanocytes (pigment cells) rau melanin pigments.β-Arbutin tau hais los ua kom pom kev ua kom tawv nqaij los ntawm kev txo qis melanin pigments los ntawm kev ua haujlwm ncaj qha ntawm tyrosinase hauv melanocytes.
