Vitamin E protects cell membranes from damage by oxygen free radicals. It can prevent premature aging of the skin induced by UV irradiation and lipid peroxidation.
Vitamin E can help to protect the skin from UV damage, as well as improving skin texture and moisture content, and studies also show it can help prevent melanin deposits, promote hair growth and improve the stability of cosmetic formulations. Vitamin E is an incredibly effective antioxidant that helps to not only preserve and lengthen the shelf life of other cosmetics, but it can prevent skin damage caused by aging and the harsh outside elements such as UV radiation, and cold. This oil is vital to the protection and preservation of skin, helping to reduce the appearance of fine lines and wrinkles as well as preventing the formation of scars and stretch marks, making it an essential cosmetic ingredient for skin care, particularly in mature skin
Vitamin E can rapidly scavenge lipid peroxyl free radicals by acting as chain breaking antioxidants, thus preventing them from reacting with other lipids. This process is key to limiting the propagation of lipid peroxidation in membranes. It should be noted that tocopherol has the potential to act as a pro-oxidant rather than an anti-oxidant when co-antioxidants like vitamin C are not available to neutralize the tocopherol radical and when oxidative stress is mild.
