Rosacea is a common skin disease that causes redness and swelling on the face. Often referred to as “adult acne,” rosacea may begin as a tendency to flush or blush easily, and progress to persistent redness in the center of the face that may gradually involve the cheeks, forehead, chin, and nose. It also may involve the ears, chest and back. As the disease progresses, small blood vessels and tiny pimples begin to appear on and around the reddened area; however, unlike acne, there are no blackheads.
It is characterized by symptoms of facial flushing and a spectrum of clinical signs, including erythema, telangiectasia, coarseness of skin, and an inflammatory papulopustular eruption resembling acne.
