Xerosis is a medical term for dry skin, which occurs when the skin loses moisture and becomes rough, flaky, or itchy. This condition can affect any part of the body but is most commonly seen on the hands, feet, and elbows. Factors contributing to xerosis include environmental conditions, such as low humidity, and lifestyle choices, like frequent bathing or using harsh soaps. Treatment for xerosis typically involves moisturizing the skin regularly with creams or lotions that contain ingredients like glycerin or urea. In more severe cases, a healthcare provider may recommend prescription treatments or lifestyle changes to help restore skin hydration and prevent further dryness.
