Free radicals – atoms is having on the outer free orbit "unpaired" electron. They are formed either in the cell as a result of its activity, either from solar radiation, or under the influence of environmentally hazardous environment. Such an electron tends "Steal" and attach itself to another electron to have a pair. Behaves very active. Today, free radicals due to cancer, heart attacks, strokes, diseases of the nervous system, the system circulation, a variety of geriatric diseases. Located near the cell membrane, free radicals can "steal"! missing electron from it. This leads to a change in the cell, disruption of the cell membrane and penetration into the cell of foreign matter.
The most dangerous thing is that free radicals can damage the cell nucleus and the genetic code (DNA), which leads to irreversible pathological changes. Influence free radicals are not spared and cosmetics. The bulk of the work of Cosmetic Scientists aim to create drugs that eliminate wrinkles and prevents premature aging of the skin. Free radicals damage the fiber collagen and elastin, leading to loss of skin elasticity and aging. However, the deleterious effect of these radicals is neutralized with so-called antioxidants. Therefore, high-quality creams contain a large number of antioxidants. For antioxidant enzymes are – a natural mechanism, which is located in the cell itself. Enzymes are designed to freely give their radical electron, without prejudice to the cell. But the cell is not always able to self to emerge victorious in this process. Very happy to scientists was the discovery of anti-free radicals – that vitamins C and E, beta-carotene, a provitamin of vitamin A.
