Moisturizing is the base of skin care treatment and relies primarily on the prevention of water loss through the skin. Moisturizing treatments therefore have the task of protecting and enhancing the natural skin barrier consisting of the stratum corneum and the hydrolipidic film on the skin surface. It also increases the ability of the stratum corneum water-binding and inhibit evaporation by creating a film on the surface of the epidermis.
The main function of epidermis is to protect the body against loss of water. Thanks to its structure and chemical composition it is almost an impenetrable barrier. It prevents skin penetration from substances from the outside and also inhibits the escape of water from deeper tissues. Adequate hydration of the skin is maintained, ensuring that the skin is healthy and not damaged.
Water is involved in all the physiological processes of the skin. Adequate hydration of the skin is very important for the proper functioning and thus for beautiful appearance. Water is the environment in which occur enzymatic reactions, that provide energy, nutrients and elements necessary for the growth and regeneration of tissues. With the right amount of water, collagen and elastin fibers can retain their proper construction and properties, providing skin elasticity, suppleness and firmness. Also, the smoothness of the skin surface depends on its adequate hydration, as it provides the correct physiological exfoliation.
