Daim Ntawv Thov

Hauv cov tshuaj pleev ib ce, tyrosinase ua haujlwm ntawm melanocytes raug txwv, thiab melanin tsim tawm raug txwv los ntawm kev txwv melanin synthetase. Nws tuaj yeem ua kom dawb thiab tshem tawm cov quav hnav, maj mam ploj thiab tshem tawm cov quav hnav, chloasma, melanosis, pob txuv thiab cov pob laus. Kev nyab xeeb siab, tsis khaus, ua xua thiab lwm yam kev phiv, sib haum zoo nrog cov khoom siv tshuaj pleev ib ce, thiab ruaj khov UV irradiation. Txawm li cas los xij, arbutin yooj yim rau hydrolyze thiab yuav tsum siv ntawm pH 5-7. Yog li kom ua tiav qhov zoo dua ntawm kev ua kom dawb, tshem tawm cov quav hnav, ua kom noo noo, ua kom mos, tshem tawm cov wrinkle thiab tiv thaiv kev o. Nws kuj tseem siv tau los tshem tawm cov liab thiab o, txhawb kev kho qhov txhab yam tsis tawm cov qhov txhab, thiab tiv thaiv kev tsim cov dandruff.
