Wopereka Mtengo Arbutin Ndi CAS 497-76-7
Arbutin adachokera ku zomera zobiriwira zachilengedwe ndipo ndi chinthu choyeretsa khungu chomwe chimagwirizanitsa mfundo za "green", "zotetezeka" ndi "zothandiza". Arbutin ndi njira yabwino yoyeretsera zodzoladzola zoyera. Pali ma isomers awiri a kuwala, omwe ndi α Ndipo mtundu wa ß, wokhala ndi zochitika zamoyo ndi ß isomer. Arbutin ndi imodzi mwazinthu zotetezeka komanso zoyera zoyera zomwe zadziwika kumayiko ena, komanso ndizopikisana nawo pakuyeretsa khungu ndikuchotsa makwinya m'zaka za zana la 21.

Mu zodzoladzola, ntchito ya tyrosinase ya melanocytes imaletsedwa, ndipo kupanga melanin kumaletsedwa ndi kuletsa melanin synthetase. Itha kuyera bwino ndikuchotsa madontho, pang'onopang'ono kuzimiririka ndikuchotsa mawanga, chloasma, melanosis, ziphuphu zakumaso ndi mawanga okalamba. Kutetezedwa kwakukulu, kusakwiyitsa, kulimbikitsa ndi zina zoyipa, kuyanjana kwabwino ndi zodzikongoletsera, komanso kuyatsa kokhazikika kwa UV. Komabe, arbutin ndi yosavuta hydrolyze ndipo iyenera kugwiritsidwa ntchito pa pH 5-7. Kuti mukwaniritse bwino kuyera, kuchotsa madontho, kunyowa, kufewetsa, kuchotsa makwinya ndi zotsatira zotsutsa-kutupa. Angagwiritsidwenso ntchito kuthetsa kufiira ndi kutupa, kulimbikitsa machiritso a zilonda popanda kusiya zipsera, ndi kulepheretsa kubadwa kwa dandruff.
