What is dry skin?
Dry skin is a very common skin condition characterized by a lack of the appropriate amount of water in the most superficial layer of the skin, the epidermis. While dry skin tends to affect males and females equally, older individuals are typically much more prone to dry skin. The skin in elderly individuals tends to have diminished amounts of natural skin oils and lubricants. Areas such as the arms, hands, and particularly lower legs tend to be more affected by dry skin. Dryness of the skin is affected by the amount of water vapor in the surrounding air, the humidity. Dry skin is also known as xeroderma or xerosis.
Dry skin may be a mild, temporary condition lasting a few days to weeks. Dry skin may also become a more severe, long-term skin problem for some. Symptoms of dry skin include discomfort from skin tightness and itching. In addition, external factors such as weather can affect the severity of skin dryness. For example, cold or dry air and winter weather can worsen dry skin. Individuals whose occupations require more frequent hand-washing and sanitizing may experience dry skin more often. Dry skin may also be a side effect of some medications or a symptom of an underlying medical disorder.
The epidermis is normally composed of fat (lipid) and protein. The lipid portion of the epidermis helps prevent skin dehydration. When the skin’s fatty oils are removed, the skin loses its protection and loses moisture more easily. As skin becomes dry, it also may become more sensitive and prone to rashes and skin breakdown. This condition is sometimes referred to as xerosis. Dry skin may be an entirely invisible skin condition, or may cause a fine dry powder-like appearance of the skin. Untreated, dry skin may become irritated and result in a red rash (xerodermatitis).
Simple prevention and treatment measures are very effective in the treatment of dry skin. Basic dry skin prevention steps include avoidance of harsh soaps and chemical cleansers. Treatment generally requires more frequent and regular applications of bland emollients and moisturizers. Untreated, dry skin may result in complications, including rashes, eczema, secondary bacterial infections, cellulitis, and skin discoloration. Fortunately, dry skin is usually mild and can be easily remedied.
