The antioxidant properties of vitamin E
Vitamin E has strong antioxidant properties, and this is the main reason why it is widely used in the production of cosmetics. The free radicals produced under the influence of many factors, including metabolism, air pollution, and ultraviolet radiation are atoms or molecules that have one or more unpaired electrons. They are actively looking for "a couple" of these electrons, and reach their goals, taking the missing electron from another molecule, turning it into a free radical, which will also search for an electron. The result is a chain reaction, which over time can lead to premature aging of the skin

and more serious problems, such as malignant diseases.

Laboratory studies have shown that the most effective tocotrienols are struggling with aging, but these were experiments conducted Only in animals.
In addition to the antioxidant, vitamin E has anti-inflammatory properties. It eliminates irritation and redness of the skin, helping it to stay longer young and healthy.
Protection from exposure to sunlight
Vitamin E provides the skin with some protection from sunlight. Studies have shown that the application of tocopherol on the skin of animals to protect them from damage that may cause the ultraviolet rays. Vitamin E also reduces the risk of severe sunburn, and even improves ingredients in sunscreen composition - for example, zinc oxide and titanium dioxide. Especially well it protects the skin of the sun cosmetics, which include those with vitamin E is vitamin C. But we should not abandon the conventional sunscreen lotions, and rely on simple creams containing Vitamin E. It reduces the likelihood of skin lesions related to exposure to sunlight but it does not function as a sunscreen filter.

and moisturizing ingredient and preservative. The fact that it protects from the sun not only the skin, but also the active ingredients of cosmetics which the light can quickly deteriorate. Therefore, vitamin E increases the shelf-life of cosmetics, particularly if it is contained in the blister packs. If vitamin E is listed at the end of the list of ingredients of cosmetic products, it means that it is included in its composition is as a preservative and not moisturizing ingredient.
Vitamin E and scar treatment
Many ointments designed to eliminate scars, contain vitamin E - is that it helps make them much less noticeable, or even completely get rid of them. Unfortunately, the results of research that does not confirm or even indicate the opposite. One recent study showed that topical application of vitamin E after surgery may badly affect the appearance of scars. Experts do not recommend the use of vitamin E for the acceleration of skin repair after surgery, since it can promote the formation of excess scar tissue. In this case it will be possible to reduce scarring only with special cosmetic procedures.
