The skin is the largest organ in the body, and when it does not retain a sufficient amount of moisture, it becomes dry.
Dry skin, unless it is an inherited disorder or is caused by another condition, is called xeroderma.
Dry skin is an uncomfortable condition causing the skin to become irritated and itchy. The skin may at times slough off in small flakes and scales. Scaling most often affects the lower legs. Rubbing or scratching dry skin can lead to infection and scarring.
