If you want to achieve the effects of whitening, antioxidation and promoting collagen synthesis by taking vitamin C, you need to take at least C 1000mg of vitamin C every day.

By taking vitamin C orally, it is absorbed by the gastrointestinal tract and then flows through various tissues of the body with blood, which inhibits the production of melanin in the basal layer of the skin, thus improving the whiteness of the skin and helping the skin to be white and clean.

If you want to take vitamin C effectively, you'd better follow two rules:

1. Take vitamin C after meals, because the absorption rate of taking vitamin C after meals is about 1.5 times that of fasting;

2, a small amount of multiple intake, because the absorption climax of vitamin C will arrive 3 hours after intake.

The brain needs vitamin c more. The report pointed out that taking 1000-2000mg of vitamin C every day not only has a good cosmetic effect, but also does not cause negative reactions to the body.
