In skin a role of the most important cells is played by collagenic fibers. This powerful framework of our skin is surrounded with liquid which is held in fabrics by hyaluronic acid. Without hyaluronic acid liquid is absorbed in environment and disappears at reckless speed. Acid possesses unique ability: it will transform liquid to gel. This gel "filler" provides elasticity of skin and health of collagenic fibers and stops all visible reasons of aging of face skin, for them the liquid environment is not only physical support, but also food.
Now we watch reports of scientists for the aging reasons: after 40 flyings in an organism of the woman there is a decrease in production of hyaluronic acid. Every year it becomes 5% less. Means, gel "filler" weakens, the amount of collagenic fibers is reduced. "Springs" become thicker and more rigid. And between "springs" under the influence of external forces folds – wrinkles are formed. Because fibroblasts (the cell living in a hypoderma) synthesize less hyaluronic acid. Unfortunately, there is it not only owing to age. Process of the reasons of aging is programmed in us genetically: someone keeps face skin youth till 50 flyings, and someone already in 30 looks not in the best way.
Of course, the reasons of aging of skin not only at age and genetic predisposition. As all of us know, any factors like solar activity, smoking, a stress and improper feeding spoil face skin. The main destroyers who bear everyone and everything on the way are free radicals. These are molecules, one of atoms of which has not coupled electron. Actually everything is simple for the aging reasons: if the electron is not coupled, it is necessary to select it at other molecule. Then other molecule becomes a free radical and goes to search of the victim. Such destruction – a molecule behind a molecule – is called chain reaction. To stop this process, antioxidants are necessary. They supply the distressful radical with not enough electron and do not collapse.
All theoretical part with which you just got acquainted brings us to the list of actions which are necessary for rejuvenation of skin. To recover qualitative and quantitative composition of collagenic fibers. To stop destructive action of free radicals. It is quite possible to carry out all these actions by means of cosmetics. Low-molecular means have an opportunity to get into deep layers of face skin and to regulate a metabolism so that skin returned itself elasticity.
