1. Inhibition ntawm tyrosinase kev ua
Tyrosinase yog ib hom polyphenol oxidase uas muaj tooj liab, uas yog cov enzyme tseem ceeb ntawm melanin synthesis.Inhibition ntawm nws cov kev ua ub no tuaj yeem inhibit qhov tsim ntawm melanin, thiab tom qab ntawd ua tiav cov txiaj ntsig ntawm kev txhim kho tawv nqaij xim thiab ua kom dawb.
2. Tshem tawm cov pa oxygen dawb radicals
Txo qhov tsis zoo ntawm exogenous yam xws li ultraviolet, oxygen dawb radicals ntawm lub physiological txheej txheem ntawm melanin tsim, thiaj li tiv thaiv daim tawv nqaij, slows laus thiab tshem tawm wrinkles.
3. soften cuticle thiab whiten daim tawv nqaij
Nws tuaj yeem soften stratum corneum, qhib cell regeneration, whiten ntawm daim tawv nqaij thiab ceev lub stratification ntawm keratinocytes.
4. Txo cov pigmentation ntawm synthesized melanin
Nws muaj kev ua haujlwm ntawm kev tiv thaiv oxidation thiab dawb radical scavenging, ncua kev laus ntawm daim tawv nqaij, inhibiting qhov tsim ntawm pigment deposition los ntawm oxidation txoj kev ntawm tshiab synthesized melanin.
