VITAMIN E IN THE HEALTH AND COSMETICS
Vitamins, taken regularly and in sufficient quantity, either in the diet or taken as supplements, they have proven effective in maintaining health. Also in recent years it has been increasing its use in skin care obtaining beneficial results. These vitamins, or antioxidants are vitamins E and C. It has been found that vitamins prevent or delay the degeneration associated with the aging process. The cells in our body are constantly exposed to free radicals (which are produced by the body's natural processes (oxidative stress) and external sources such as pollution, snuff, ...) that cause the effects we call aging. Vitamins E and C are two powerful weapons against free radicals. Vitamin E is known for its qualities as an antioxidant and as protector of cell membranes against free radicals and the harmful effects of the sun. It is also known that works best in the presence of synergists such as vitamin C. It is well established that vitamin C plays an important role in the synthesis of body collagen, which is responsible for skin elasticity. Applying Vitamin C directly on the surface of skin collagen synthesis which enhances elasticity is stimulated, inverts the thinning of the skin that occurs with age and provides lasting protection against sun damage. It has been scientifically proven that Vitamin C helps refine the lines, improving wrinkles, skin conditioning and prevents aging prematuro.La accumulation of hydroperoxides lipids in the membrane may disrupt its function and cause its collapse. They can also be decomposed to give a wide range of cytotoxic drugs, most of which are aldehydes (malonaldehyde, 4-hydroxynonenal ...) that may cause severe damage to membrane proteins. Vitamin E being liposoluble, it concentrated inside the cell membrane in strategic positions to combat free radicals and interacts with Vitamin C (water soluble) found in the extracellular fluid.
