Will taking vitamin C in summer make you darker?

Young female friends have been committed to skin care and whitening since their student days. Many people will incorporate whitening into their diet, such as lemons and tomatoes. Everyone knows that lemons are rich in vitamin C, which has a whitening effect. However, it is not suitable to eat foods containing vitamin C or apply cosmetics containing vitamin C during the day, otherwise it will have the opposite effect. This article introduces the reasons behind this, let’s take a look.

In summer, vitamin C and vitamin E need to be applied at night. If applied during the day, they will easily absorb ultraviolet rays when going out, and the strong light will make the skin darker, so it is best to use them at night. Using them at night can achieve the purpose of anti-oxidation, whitening and freckle removal.

Because VC is photosensitive, your skin will turn yellow if you eat it during the day, and will turn dark over time, so it is better to eat it at night. Another thing is to do a good job of protection. If you often face the computer, try to eat less photosensitive foods during the day, such as carrots, eggplants, etc. . .

Our skin loses some moisture every day. Coupled with factors such as ultraviolet rays, air-conditioned rooms and pressure, it will cause skin physiological disorders, dull skin and prone to aging. Of course, fair and flawless skin is the symbol of beauty, so whitening is something that we beauty-loving ladies must do every day.

Vitamin C is widely used in cosmetics. It can not only whiten the skin, perform oxidation-reduction functions, but also promote collagen production. Today we will look at these effects of VC.

Why does our skin become darker and the principle and effect of VC

Tyrosine, the precursor of melanin, exists naturally in epidermal cells. When our skin is exposed to ultraviolet rays, it automatically triggers a series of reactions that convert tyrosine into melanin, the so-called melanin. There is a key substance in this reaction - tyrosinase. Tyrosine is converted into DOPA by tyrosinase, which then converts DOPA into DOPAquinone, which is then self-oxidized into melanin.

Vitamin C can inhibit the activity of tyrosinase, hinder the production of melanin, protect the skin from damage by ultraviolet rays, and improve the effect of dull skin.

In addition, vitamins have an exciting effect, promoting collagen production. It is very sad that women lose collagen very quickly after the age of 20. Collagen can be said to be the skeleton of the skin. It gives strength to the skin and maintains the structure of the skin. Without collagen, the skin loses its elasticity and wrinkles appear. Vitamin C can play an antioxidant and anti-aging role, and promote the proliferation of collagen, which has anti-wrinkle and anti-aging effects.

Therefore, if you want to have fair and smooth skin, you need to supply rich vitamin C every day. However, vitamin C is a water-soluble vitamin and will be excreted through sweat and urine, so we need to take it in from food every day. Vegetables and fruits contain a lot of vitamin C, so we need to eat more vegetables and fruits in our daily life.
