With dry skin, the skin is flaky and may have a rough or rough surface. The skin feels less soft and flexible, and cracks more easily. Itching and skin irritation are common and bothersome. Some develop eczema with red, flaky and thickened skin.
Disturbances in the epidermis' fatty substances and the epidermal cells weaken the skin's ability to retain moisture. The skin's barrier deteriorates. The causes of dry skin are old age, low humidity, excessive body washing and use of soap. In particular, the hands become dry through frequent washing or the use of alcohol. Other causes can be hereditary, for example in the case of the skin disease ichthyosis. People who have or have had atopic eczema, pollen allergy or asthma tend to have dry skin. This particularly applies to children.
Frequent use of moisturizers is important, preferably several times per day. Moisturizers have different compositions of fatty substances such as petroleum jelly and paraffin, and other moisture-binding substances such as carbamide and glycerol. Choice of moisturizer is influenced by severity, preference, availability and price. Excessive body washing, irritating soap and friction from coarse textiles and wool should be limited. Showering and washing should last a short period and the water should not be too hot. Shower oils can be used. In case of eczema, cortisone creams are appropriate, and medical attention may be necessary.
