Itchy skin is an uncomfortable, irritating sensation that makes you want to scratch. Also known as pruritus, itchy skin is often caused by dry skin. It's common in older adults, as skin tends to become drier with age. Many people find relief with self-care measures such as moisturizing daily, using gentle cleansers, and bathing with lukewarm water. Long-term relief requires identifying and treating the cause of itchy skin. Common treatments are medicated creams, moist dressings, and oral anti-itch medicines.
