Rosacea is a skin disease typically appearing in persons during their 30s and 40s. It is marked by redness (erythema) of the face, flushing of the skin, and the presence of hard pimples (papules) or pus-filled pimples (pustules) as well as small, visible spider-like veins called telangiectasia. In later stages of the disease, the face may swell and the nose may take on a bulbous appearance, a condition called rhinophyma.
