我們所熟悉的維他命C，是一種抗氧化劑，可預防紫外線對皮膚造成的傷害、抑制黑色素，發揮淡斑、美白的功效，也可以幫助抵抗肌膚的衰老。但人體無法自製維他命C，只能靠外在補給。

到底要口服還是外塗的效果才會最好？

其實，由食物攝取到的維他命C，會到達皮膚細胞的有限，只有約7%能成功抵達。有研究發現，外塗相比口服，可使皮膚細胞吸收多20倍的維他命C，因此外塗是更有效。

不過維他命C本身份子非常不穩定，很容易被氧化，功效大大降低。但維他命C美白粉 就絕無這問題，即制即用，既新鮮，效果又好。

Vitamin C, which we are familiar with, is an antioxidant that prevents damage to the skin caused by UV rays, inhibits melanin, exerts blemishes and whitens, and also helps fight skin aging.  However, the human body cannot make Vitamin C, and must rely on external supply.

Is it best to use it orally or externally?

In fact, Vitamin C ingested from food can reach a limited number of skin cells, and only about 7% can reach it successfully.  Some studies have found that external application can make skin cells absorb 20 times more Vitamin C than oral administration, so external application is more effective.

However, Vitamin C is very unstable, it is easily oxidized, and its effectiveness is greatly reduced.  But Vitamin C powder will never have this problem, it is ready to use and it is fresh and effective.

 🍋 Usage:
Mix a pea sized amount of Vitamin C powder into the toner, apply it evenly (do not use too much, it is ineffective and has a tingling sensation).
