What Causes Dry Skin?
Dry skin can be caused by a number of factors. Genetics plays a role in the development of dry skin. Oil glands that do no supply enough sebum will not be able to lubricate the skin properly. Dry skin can be caused by environmental factors such as exposure to sun, wind, cold, chemicals, or cosmetics, or excessive bathing with harsh soaps. The oil glands do not supply enough lubrication to the skin. As a result, the skin becomes dehydrated. Diet also plays a role in the lubrication of the skin. A poor diet that is lacking in essential nutrients, especially deficiencies of vitamin A and the B vitamins, can cause the skin to become dry.
Skin conditions such as dermatitis and eczema may aggravate the skin and cause it to become dry, flaky, and dull. Medical conditions such as hypothyroidism and diabetes may develop dry skin as a side effect of their condition or of the medication they are talking. Other medications, such as diuretics, antispasmodics, and antihistamines can contribute to dry skin.
