Alternate Names : Asteatosis
Dry skin occurs when the moisture, or water, content of the skin
is decreased for any reason.
What is going on in the body?
The surface of the skin holds a certain amount of water. When the water content
decreases, the skin becomes dry, itchy, and uncomfortable.
What are the causes and risks of the symptom?
Some individuals have a genetic predisposition to dry skin. As
people age, their skin
tends to become drier. Dry air, resulting from winter's low humidity and the use
of indoor heat, can cause skin to dry out. Long, hot baths and showers can also
make skin dry.
