style="text-indent:25px">VC乙基醚,也叫維生素C乙基醚,是采用擁有一步合成法,合成的高純度維C衍生物，與維生素C (VC)有著本質(zhì)上的區(qū)別。維生素C(VC)以其高效淡斑美白作用以及高安全性得到認(rèn)可,但其本身極易被氧化,不易被皮膚真正吸收，皮膚利用度低。相對(duì)維C而言, VC乙基醚很容易穿透角質(zhì)層進(jìn)入皮革層，進(jìn)入皮膚后被生物酶分解轉(zhuǎn)化為VC和H2O,從而發(fā)揮VC的作用提高VC的利用度,從而起到很好的淡斑美白功效?，F(xiàn)用于凝膠、精華素、乳液、膏霜等美白淡斑、**老及其它護(hù)膚品中。維生素C乙基醚使皮膚變得充盈富有彈性，使肌膚細(xì)膩光滑。</p><div
