Skin aging is a natural process, progressing with human age. Skin constituting the greatest organ undergoes constant influence of various factors enhancing the aging processes. Among them the following can be included: endogeneous aging, the one connected with hormonal disorder, genetic conditioning and individual facial expression. These causes may be fastened by exogeneous factors of skin aging resulting from excessive exposition to the sun and pollution as well as inadequate diet. Typical symptoms of skin aging is its dryness, change of complexion and lack of elasticity. In the present paper scientific research on the influence of nutricosmetics on the functioning of skin is presented. Several groups of biologically active compounds are described which have a favourable influence on the skin state in the fight with aging, which are, among others: amino acids, polyphenols, fatty acids and probiotics. The research indicates that vitamin E, glutathione, phenolic compounds and carotenoids suppress the reactive forms of oxygen (RFO). According to the free-radical theory of skin aging, the level of RFO may increase rapidly, which leads to damage of cell structures. Presence in the diet of fatty acids from the family omega-3 and omega-6 leads to improvement of appearance and slowing down the skin aging process. Probiotics, in turn, influence significantly functioning of the whole human organism. By hindering the development of pathogenetic microorganisms they prevent, among others, intestinal infections, they regulate lipid and glycemic profile as well as they act immunomodulating. Thanks to this activity they affect indirectly skin condition and inhibit the development of atopic dermatitis.
