For chemists, hyaluronic acid is a loposaccharide of animal origin, for you - a component of the natural moisturizing factor of your skin, it is also called NMF and stands for Natural Moisturizing Factor. Actually, it is a film covering the epidermis, on which the well-being and the degree of moisture of the latter depend.

Molecules of hyaluronic acid work on the principle of a magnet: attracted to their own and thus saturate the skin with moisture. The trouble is that with age or under the influence of external factors, the concentration of this acid in the body is catastrophically reduced, then the epidermis also loses its ability to moisten itself.

Official duties of fatty acids
The lipid film that protects your skin is nothing more than the accumulation of fatty acids. Their body synthesizes itself, and they are called saturated.

Do you feel that the skin is peeling and capricious? She needs help, which you can always get from cosmetics. Look for linoleic, linolenic, gamma-linolenic and omega-3 fatty acids in creams.

In general, hyaluronka benefits any skin, but if yours is dry, this acid is necessary to it, like water to a person. But even in this case, the concentration of active substance in the care composition should not exceed 1%. Creams with fatty acids are universal companions. Suitable for everyone, save from various ailments, revive the weather-beaten skin and suffered an unsuccessful chemical peeling.

If we are talking about salon care, then after them the face is restored in seven days, so it is not advisable to conduct rituals on acid more than once every two weeks. In what quantity - only a cosmetologist can tell by looking at you.
