Vitamin E, also known as tocopherol, is not produced by ourselves but must be obtained through our diet. It is found in fresh vegetables, vegetable oils, grains, and nuts, among other sources. It is an important vitamin for your entire body, and even essential for your skin. Naturally, vitamin E is the most abundant vitamin in the skin, particularly the layer of dead skin cells. The vitamin is absorbed through our bodies into the sebum, which then reaches the outermost layer of skin. Research has shown that many people have a vitamin E deficiency.
