Rosacea is a skin disorder. It causes chronic redness of the face. It can also cause swelling, tiny pimples, and the appearance of broken blood vessels. Rosacea usually affects the cheeks, forehead, chin, and nose. The ears, chest, and back may also be affected. More than half of people with rosacea also have mild eye symptoms. This may include redness, burning, and watering. This is known as ocular rosacea.
