辅酶Q10又称泛醌,是一种强亲脂性抗氧化剂,它在化妆品中作抗氧化剂、保湿剂和皮肤调理剂使用。存在于心脏、肾脏、肺肝、肌肉等重要脏器和皮肤细胞中,是线粒体电子传递和氧化作用的重要介质,参与代谢,为细胞提供能量,提升细胞活力。作为一种小分子物质能够很容易穿透肌肤,起到提高皮肤修复再生能力,减少自由基损伤,达到抗衰老的作用。它对于预防光老化和皱纹有很好效果,特别是眼部的鱼尾纹。其作用机理为:参与细胞的基本生化反应,主要作用于氧化磷酰化反应中的电子传导,其分子中的苯醌结构能可逆地加氢还原而形成对苯二酚的衍生物,是生物氧化反应中的一种“递氢体”辅酶,主要能提高皮肤的生物利用率。辅酶Q10遇光易分解,如波长为360nm的紫外线或透经玻璃的光,颜色就会变深;也易被碱破坏,焦性没食子酸可抑制碱对辅酶Q10的伤害。目前为止,未见辅酶Q10外用不安全的报道。

Thanks to Nivea, Q10 is a pretty well-known ingredient and the fame and Beiersdorf's (the parent company of Nivea) obsession with it are not for no reason. It's an antioxidant found naturally in human cells where it plays a big role in energy production.

In fact, it's so important for energy production that if taken as an oral supplement it has a caffeine-like effect and if taken at night you will probably not sleep very well (so you should take it in the morning). Q10 supplementation is not a bad idea: it not only gives you energy but research also shows that oral Q10 increases the Q10 level of the skin (of course, it decreases with age like pretty much every good thing in the skin) and may help to reduce wrinkles.
