Rosacea is a chronic (long-term) skin disease that causes redness and swelling. Although it is primarily on the face, other areas that can be affected are the scalp, neck, ears, chest and back and sometimes 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. Since rosacea causes facial swelling and redness, it is easily confused with other skin conditions, such as acne and sunburn. For this reason, rosacea is known as the “great pretender,” and often incorrectly referred to as “adult acne.”
