Powerful Strength VC Serum 20% Vitamin C Serum For Face
The main reason why vitamin C has whitening is because it inhibits tyrosinase and inhibits the formation of melanin. At the same time, vitamin C is also involved in the synthesis of gelatin and mucopolysaccharide, so it can also promote wound healing.
1. Vitamin C can whiten skin
Because it can help the skin resist UV rays, avoid dark spots and freckles, many whitening products are added with vitamin C, which is considered to be very white.
In summer, it can prevent skin damage after sun exposure, promote metabolism, let out the formed melanin, and dilute spots.
In autumn and winter, it can change the darkness of the skin due to poor blood circulation.
It can also help the skin to lock in the necessary moisture, avoid peeling and tightness caused by excessive evaporation, strengthen the skin's ability to resist external pollution, and avoid skin fatigue and sallow ugly.
2. Vitamin C can eliminate acne.
Vitamin C is easily oxidized and difficult to store, so it is quite limited in the use of skin care products. Vitamin C in many skin care products is now chemically treated, making them less susceptible to wear and tear, and also enhances the penetration of the skin, thereby destroying the synthesis of melanin, so that whitening effect can be exerted.
The emulsion containing vitamin C can whiten the skin and reduce fine lines and dark spots because it can directly penetrate the skin and repair the damage and aging caused by ultraviolet rays.
Because it can improve the efficacy of treating acne, whitening, etc. Recently, high concentrations of vitamin C are often used in the treatment of skin.
3. Vitamin C can remove melanin.
The color of the skin depends mainly on the amount of melanin in the skin. The root of melanin production is tyrosinase. The tyrosine in melanocytes is converted to dopaquinone by its action, and then oxidized to form true melanin. The formed melanin gradually reaches the surface of the skin along with the normal metabolism of the skin, and finally peels off together with the aged keratin. If the face skin is not well metabolized, it will cause a large amount of pigmentation and local accumulation, and the skin will be darker or spotted to cause uneven skin. Therefore, inhibition of tyrosinase biosynthesis and sun protection is the key to whitening.

The whitening principle of vitamin C
First, there are many factors that determine whether our skin is black or white, such as heredity, sun exposure, endocrine hormone levels, etc., but in general, the color of the skin depends mainly on the amount of melanin in the skin. The origin of melanin production is tyrosinase. Tyrosine in melanocytes forms true melanin to the surface of the skin after a series of chemical and oxidation reactions. If the skin is not well metabolized, it will cause a large amount of pigmentation and aggregation. The color of the skin will be deepened or spots will form uneven skin, which will make people black. Therefore, inhibition of tyrosinase biosynthesis is the key to whitening. Vitamin C can inhibit the activity of tyrosinase, block the production of melanin, has certain antioxidant properties, and can reduce the formed melanin into a colorless melanin precursor, thereby improving the dullness of the skin to achieve whitening effect.
