Picture of Xerosis
Xerosis. Xerosis is the medical term for abnormally dry skin. It's often an inherited condition but can also be a sign of aging. It is characterized by rough, dry skin that often cracks. Try to seal in the moisture from a lukewarm bath or shower with a cream or oil-based product, and moisturize your skin throughout the day. Avoid long hot showers as they are very drying.
