How can vitamin C help my skin?
维生素C如何护理皮肤？
So vitamin C is a potent and well-studied antioxidant that has multiple benefits for the skin.
维生素C是一种经过充分研究的有效抗氧化剂，对皮肤有多种益处。
When use topically this antioxidant can bind to something that we call free radicals.
局部使用时，这种抗氧化剂可以与所谓的自由基结合。
So free radicals are what are created in our skin and in our body as a result of a variety of different environmental stressors including things like UV rays or excessive sun exposure.
自由基是由于各种不同的环境压力因素（包括紫外线或过度阳光照射）而在皮肤和身体中产生的。
The free radicals are unstable molecules that can wreak havoc in our body.
自由基是不稳定的分子，会对身体造成严重伤害。
In our skin they can accelerate collagen breakdown, leading to issues like wrinkle development, and also affect the function of the superficial skin cells, leading to things like hyperpigmentation, sunspots.
在皮肤中，自由基可以加速胶原蛋白的分解，产生皱纹，并且还会影响浅层皮肤细胞的功能，导致色素沉着过度、雀斑等问题。
So when vitamin C is used consistently, it can actually help remodel and build collagen, which can then reduce fine lines of wrinkles.
坚持使用维生素C，可以帮助重塑和生成胶原蛋白，从而减少细纹。
It can also help the superficial skin cells to function more properly, resulting in more of a bright and even complexion.
它还可以帮助表层皮肤细胞更正常地发挥作用，从而使肤色更加明亮均匀。
So I recommend using a vitamin C serum in the morning after you wash your face, prior to applying sunscreen.
因此，我建议早上洗脸后、涂抹防晒霜之前使用维生素C精华液。
And I like to use vitamin C in the morning because the antioxidant properties can really support the skin protective properties of sunscreen.
我喜欢在早上使用维生素C，因为它的抗氧化特性确实可以支持防晒霜的皮肤保护特性。
I do think that this is one of those skincare products that is worth splurging on.
我认为这是值得花钱购买的护肤品。
Vitamin C can be like very delicate molecule so I recommend finding one that's like well formulated and well packaged.
维生素C就像非常脆弱的分子，因此我建议寻找配方良好且包装良好的分子。
