Dry skin

Healthy skin is smooth and soft and provides protection against penetration by bacteria, allergens or chemical substances. In particular, the outermost layer of skin, the horny layer, serves as a barrier against excessive moisture loss. For this, the horny layer requires an even balance of lipids and moisture. The so-called hydro-lipid system is responsible for this, a natural protective mantle of water, lipids (skin oils) and moisture-binding substances. These are located like a kind of mortar between the horny, dead skin cells ('brick-and-mortar model').

If the relationship between the individual components of the hydro-lipid system is disturbed, e.g. through too frequent washing with hot water or too much soap, the barrier function cannot be upheld. Result: The skin becomes rough, scaly, cracked and sensitive, with a tendency to redness and inflammation. The dry skin itches and is taut. It has a tendency to form small wrinkles, particularly on the face. Frequently affected areas of the skin are the face, the extensor sides of the upper and lower arms, hands, shins and feet.
