Is there a permanent cure for scaly skin, or is it incurable?

Scaly Skin. Scaly skin is a common symptom of dry skin and can occur anywhere on the body, although it is most common on the lower legs, arms and thighs. While scaly skin can be caused by a variety of conditions, most scaly skin will result from natural processes or environments, such as normal aging or cold, dry environments. See your doctor for a diagnosis and treatment.
