Rosacea (rose-AY-sha) is a chronic (long-term) skin disease that causes redness and swelling, primarily on the face. Other areas that can be affected are the scalp, neck, ears, chest and back. Sometimes, rosacea affects the eyes.
Those afflicted with rosacea may first notice a tendency to flush or blush easily. The condition can occur over a long period of time and often progresses to a persistent redness, pimples and visible blood vessels in the center of the face that can eventually involve the cheeks, forehead, chin and nose.
