Cosmetics added with vitamin E have significant effects on skin, mainly in:
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.
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.
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.
