Cosmetics added with vitamin E have significant effects on skin, mainly in:
Sun protection
UV radiation will produce highly active free radicals, then leading to oxidative damage to skin cells or tissues. The maximum absorption peak of is near 286 nm, and it has a strong absorption effect. Tocopherol is more effective against UVB radiation. Therefore, tocopherol applied on skin has a certain effect of absorbing and filtering ultraviolet rays.
Anti-aging
The study proves vitamin A, vitamin C, natural vitamin E with fucose can better regulate biosynthesis of fibroblast collagen. This shows that tocopherol has a synergistic effect against skin aging.
Moisturizing
Natural vitamin E can inhibit loss of skin moisture. It makes skin moist and shiny; it can prevent destruction of components (lipids and proteins) in the cell membrane. Thereby, lipids and other components can better bind water molecules. Vitamin E prevents moisture loss by directly moisturizing and infiltrating inside, so the moisturizing effect is significantly higher than ordinary glycerin moisturizer.
