The essence of vitamin E is a fat-soluble vitamin. It has many functions. Here is an important point: it is an extremely important antioxidant, which can remove peroxy free radicals in the human body and reduce the damage of free radicals to cells; and can penetrate into the cell membrane, help antioxidant, reduce oxidative damage.
In terms of whitening, vitamin E plays a more preventive role
In the process of melanin production, the damage of free radicals can stimulate the skin to synthesize melanin, and VE(vitamin E) inhibits the activity of tyrosinase by resisting free radicals to prevent the formation of melanin. Therefore, in terms of whitening, the most that VE can do is a preventive effect, and it is an indirect effect, and it cannot have an effect on the already generated melanin.
And vitamin E is an important antioxidant in the stratum corneum of the skin. How important is antioxidant? For example, when you don't pay attention to sun protection, UVA and UVB enter your skin, and antioxidants help you absorb them and reduce the damage of ultraviolet rays to your skin; another example is ozone, vitamin E is judged to have a bad effect on the skin, so help you remove it.
