Itchy skin is an
uncomfortable, irritating sensation that makes you want to scratch. Also known
as pruritus (proo-RIE-tus), itchy skin is usually caused by dry skin. It's
common in older adults, as skin tends to become drier with age.
Depending on the cause of your itchy skin, it may appear normal. Or it may be
red or rough or have bumps or blisters. Repeated scratching can cause raised,
thickened areas of skin that may bleed or become infected.
Self-care measures such as moisturizing, using anti-itch products and taking
cool baths can help relieve itchy skin. Long-term relief requires identifying
and treating the cause of itchy skin. Itchy skin treatments include
medications, wet dressings and light therapy.
