Rosacea is a chronic skin condition that causes redness and swelling of the face that can also affect the scalp, neck, ears, chest, and back. Eye symptoms (ocular rosacea) are also reported by half of people with rosacea.
Those afflicted with rosacea may first notice a tendency to flush or blush easily. The condition progresses to persistent redness, pimples, and visible, threadlike blood vessels (telangiectasias) in the center of the face. These skin changes can eventually spread to the cheeks, forehead, chin, and nose.
