Arbutin, zinthu zachilengedwe zoyera zogwira ntchito

Arbutin ndi mankhwala a hydroquinone glycoside, dzina lake la mankhwala ndi 4-Hydroquinone-alpha-D-glucopyranoside (4-Hydroquinone-alpha-D-glucopyranoside), yomwe imapezeka muzomera monga bearberry ndi bilberry. Ndi chilengedwe choyera choyera chomwe chimachokera ku Chemicalbook chomwe sichimakwiyitsa, chosasokoneza komanso chogwirizana. Pali magulu awiri ogwirira ntchito komanso ogwirira ntchito m'maselo a arbutin: imodzi ndi yotsalira ya glucose; ina ndi phenolic hydroxyl gulu. Thupi la α-arbutin ndi loyera mpaka ufa wotuwa, womwe umasungunuka mosavuta m'madzi ndi ethanol.

Ntchito ndi Kugwiritsa Ntchito

1. Whitening effect: Alpha Arbutin imatengedwa kuti ndi yothandiza kwambiri poyera. Itha kulepheretsa ntchito ya tyrosinase, kuchepetsa mapangidwe ndi kuyika kwa melanin, ndikuchepetsa bwino mavuto amtundu wa khungu monga mawanga akuda, mawanga ndi mawanga a dzuwa. Nthawi yomweyo, imatulutsa kamvekedwe ka khungu ndikuwunikira khungu losalala.

2. Imalepheretsa kupanga melanin: Alpha arbutin imatha kusokoneza kaphatikizidwe ka melanin, kuletsa ntchito ya oxidase ya tyrosine, ndikuletsa mapangidwe a melanin. Izi zimapangitsa kukhala chinthu choyenera chosamalira khungu chomwe chimalepheretsa kuchuluka kwa melanin, kuchepetsa chiopsezo cha hyperpigmentation ndi mapangidwe a zilema.

3. Chitetezo ndi kukhazikika: Poyerekeza ndi zinthu zina zoyera, Alpha Arbutin ali ndi chitetezo chokwanira komanso kukhazikika. Sichidzataya ntchito yake chifukwa cha kuwala kapena okosijeni, ndipo imatha kukhalabe yoyera kwa nthawi yayitali. Kuphatikiza apo, alpha arbutin amawonetsa kupsa mtima pang'ono pakhungu ndipo ndi yoyenera pakhungu lamitundu yonse.

4. Moisturizing ndi anti-oxidation: Kuphatikiza pa kuyera, alpha arbutin imakhalanso ndi zokometsera komanso anti-oxidation zotsatira. Zitha kuwonjezera chinyezi cha stratum corneum, kusintha chinyezi pakhungu, ndikuchepetsa kuuma komanso kulimba kwapakhungu. Nthawi yomweyo, imachepetsa ma free radicals, imateteza kupsinjika kwa okosijeni, komanso imateteza khungu ku kuwonongeka kwa chilengedwe.
