2, vitamin C beauty effect
1, Vitamin C's skin-beautifying effect Many whitening products have added vitamin C, which is considered to have great whitening effect because it can help skin resist ultraviolet rays and avoid the generation of black spots and freckles. Summer can prevent skin damage after sun exposure, promote metabolism, let melanin that has been formed be discharged, and fade spots.
In autumn and winter, it can change the dull phenomenon of skin due to poor blood circulation. It can also help the skin to lock 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 complexion.
2. Vitamin C is one of the most important factors to maintain skin health. It can eliminate dull complexion, restore skin luster and firmness, maintain skin's natural moisturizing function and effectively remove free radicals.
How about VC whitening? However, because vitamin C is easy to be oxidized and difficult to store, its application in skin care products is quite limited. Nowadays, many skin care products chemically treat vitamin C, so that it is not easy to lose, and it can also enhance the permeability to the skin, thus destroying the synthesis of melanin, thus achieving the effect of whitening.
The emulsion containing vitamin C can directly soak the skin and repair the damage and aging caused by ultraviolet rays, so it can whiten the skin and reduce fine lines and dark spots. Recently, high concentration of vitamin C is often used for skin treatment, because it can improve the efficacy of acne treatment and whitening.
3. How does the cosmetic effect of vitamins remove melanin? The color of skin mainly depends on the content of melanin in skin. The source of melanin production lies in tyrosinase.
Tyrosine in melanocytes is transformed into dopaquinone under its action, and then oxidized to form true melanin, which gradually reaches the skin surface with the normal metabolism of skin, and finally falls off naturally with aging keratin.
If the skin metabolism is not smooth, it will lead to a large number of pigment precipitation and local accumulation, and the skin color will deepen or form spots to cause uneven skin.
Therefore, inhibiting tyrosinase biosynthesis and sun protection are the keys to whitening. Vitamin C can inhibit the activity of tyrosinase, block the production of melanin, protect the skin from ultraviolet rays, reduce the formed melanin to colorless melanin precursors, and improve the dull skin effect.
Of course, there is no guarantee that melanin will not be produced again after it is reduced to colorless state. True whitening requires not only vitamin C, but also ingredients that can inhibit melanin production and effective sun protection.
