When choosing cosmetics, give preference to products with a neutral pH, because they protect the skin well from wilting and premature aging. The skin has its own natural protective barrier, which is called the acid mantle. This mantle is a kind of natural invisible film on the surface of the skin that protects it from such harmful substances as bacteria and pollutants in the environment. Any substance with a high content of alkali - including many cosmetic products with an unbalanced pH - leads to times * | the destruction of acid cover, which loses the ability to maintain the delicate balance of your skin.
