Slide show: Common skin rashes

Rosacea (roe-ZAY-she-uh) is a chronic, long-term skin condition of adults that causes redness in the face and may produce small red or pus-filled bumps.

Most people experience occasional flare-ups, usually in response to factors that increase blood flow to the surface of your skin. Triggers vary from person to person. Possible triggers include certain foods, skin products, extreme temperatures, alcohol consumption, emotional stress and sun exposure.

Rosacea has no cure, but treatments may control or reduce your signs and symptoms.
