Vitamin C ethyl ether yog ib qho vitamin C derivative uas muaj txiaj ntsig zoo heev. Nws tsis yog tsuas yog ruaj khov heev hauv cov tshuaj lom neeg xwb, nws yog ib qho vitamin C derivative uas tsis hloov xim, tab sis kuj yog ib qho lipophilic thiab hydrophilic amphoteric substance, uas nthuav dav nws qhov kev siv, tshwj xeeb tshaj yog hauv cov tshuaj lom neeg txhua hnub. 3-O-ethyl ascorbic acid ether tuaj yeem nkag mus rau hauv dermis yooj yim los ntawm stratum corneum. Tom qab nkag mus rau hauv lub cev, nws yooj yim heev rau decomposed los ntawm cov enzymes biological los ua lub luag haujlwm biological ntawm vitamin C. Nws tuaj yeem tiv thaiv kev tsim melanin, txhim kho daim tawv nqaij ci, thiab muab daim tawv nqaij elasticity, anti-oxidation thiab lwm yam haujlwm.
