Basa uye Kushandisa

1. Whitening mhedzisiro: Alpha Arbutin inoonekwa sechinhu chinoshanda chekuchenesa chinhu. Inogona kutadzisa kuita kwe tyrosinase, kuderedza kuumbwa uye kuiswa kwe melanin, uye nekunyatso kuvheneka matambudziko eganda senge rima makwapa, freckles uye mavara ezuva. Panguva imwecheteyo, inofananidzira toni yeganda uye inopenya ganda rakasviba.

2. Inhibit kugadzirwa kwe melanin: Alpha arbutin inogona kuvhiringidza nzira ye synthesis ye melanin, inhibit basa re oxidase ye tyrosine, uye inodzivisa kuumbwa kwe melanin. Izvi zvinoita kuti ive yakakodzera ganda rekuchengetedza iyo inovharira kuwanda kwe melanin, kuderedza njodzi ye hyperpigmentation uye kuumbwa kwakashata.

3. Kuchengeteka uye kugadzikana: Kuenzaniswa nezvimwe zvichenera zvinongedzo, Alpha Arbutin ine kuchengetedzwa kwepamusoro uye kugadzikana. Iyo haizorasikirwe nebasa rayo nekuda kwechiedza kana oxidation, uye inogona kuchengetedza kuchena kwayo kwenguva yakareba. Mukuwedzera, alpha arbutin inoratidza kushatirwa kwakaderera kune ganda uye inokodzera marudzi ese eganda.

4. Moisturizing uye anti-oxidation: Pamusoro pekuita chena, alpha arbutin inewo inonyorovesa uye inorwisa-oxidation mhedzisiro. Inogona kuwedzera hunyoro hwemukati we stratum corneum, kuvandudza hunyoro hweganda, uye zvinobudirira kubvisa kuoma uye kusimba kweganda. Panguva imwecheteyo, inoderedza mahara radicals, inodzivirira kubva kune oxidative kusagadzikana, uye inodzivirira ganda kubva mukukuvadzwa kwezvakatipoteredza.
