VC is whitening, because vitamin C has strong reducibility, so taking it can also play an antioxidant role, and increase skin immunity and prevent some skin problems. But m should pay attention. You studied biology in high school. This vitamin cannot be synthesized by itself in the human body. It can only be absorbed by the outside world, not accumulated in the body for a long time, so keep eating and eating.
Relying on health care products is not a cure. A lot of vitamins C and E come from daily diet. You can check foods rich in these vitamins, a lot. Just pay attention to eat more at ordinary times.
VE has a certain effect on reducing scars and pockmarks, but it must be adhered to for a long time, taken orally and applied externally to scars every night. It is a good moisturizing material to apply paper mask to the face of vitamin E milk. You can also apply proper amount to eyelashes with a mascara brush to nourish eyelashes and make them thick.
VE can effectively dilute scars to some extent, but it is not particularly obvious. It is impossible to completely remove scars with it, but you can try.
As for which one to choose, there are many brands of this one. At present, there are many health houses on the market, and the prices are relatively low, which can cater to the vast majority of people. These are two kinds of food I eat, and others are just not eaten in advertisements, so I have no right to speak.
I hope it can be used for reference for you.
