When free radicals attack polyunsaturated fatty acids (PUFA) Vitamin E prevents the hydroperoxide radicals (ROO ·), which rapidly propagate chain, and consequently the structure and functionality of the cell membrane alter formation. That is, the Vitamin E neutralizes ROO · radicals thus maintaining the integrity of the membrane. The antioxidant synergism between natural tocopherols (Vitamin E) and Vitamin C is well established. Both compounds are involved in vivo and in vitro with redox reactions related to auto-oxidation. Cell membranes and plasma lipoproteins contain Tocopherol natural, which acts as a chain breaking antioxidant. It is a highly lipophilic molecule that is located within biological membranes. Vitamin C is soluble in water. The chain breaking reactions convert Tocopherol its radical. This radical is nonreactive and does not react with the fatty acids. However, the radical Tocopherol tends to migrate to the surface of the membrane and is converted again by reaction with Tocopherol Vitamin C (Ac. Ascorbic). Thus Tocopherol Vitamin C and begin to counter the consequences of lipoproteins and peroxidation in membranes at the beginning of this process. In systems lipid-water autoxidation depends on reactions of radical changes between Tocopherol and Vitamin C. This has been demonstrated in in vivo experiments and models using a phase micelles or liposomes in which the tocopherol is present with the substrate ( linolate) and another aqueous phase with Vitamin C. In other words during the defense mechanism Vitamin E it is oxidized and loses its ability to fight free radicals, but being in contact with Vitamin C, it reduces it to its biochemically active form. For this reason it is more effective in the presence of synergists such as Vitamin C. In short: Vitamin E has anti-inflammatory and hypoallergenic characteristics that make it suitable for all skin types, is a powerful antioxidant, is effective against the harmful effects of free radicals (anti-aging), protects and repairs skin from sun impairment, reduced lines and facial wrinkles, and softens the skin. As vitamin E and natural tocopherols are, and can be widely used in almost all current formulations of gels, creams and existing capsules on the market (shampoos, gels, hand creams, creams rejuvenating and protective capsules vitamin E with aloe vera oil, etc.) Its use is also due to its protective effect for the remainder of the components of the creams, gels and capsules, since being a great antioxidant, also protects against oxidation the lipid phase of the cosmetic preparations (thus lengthening the life of these products). In this way it allows the active compounds, essential oils and fragrances stay longer actively improving their performance.
