Rosacea is a long-lasting (chronic) skin disease that affects the face, primarily the forehead, nose, cheeks, and chin. The signs and symptoms of rosacea vary, and they may come and go or change over time.
There are three main types of rosacea, categorized by their primary signs and symptoms. Erythematotelangiectatic rosacea causes skin redness and warmth (flushing) and visible clusters of blood vessels (telangiectasia). Papulopustular rosacea causes skin redness, swelling, and pus-filled bumps called pustules. Phymatous rosacea is characterized by thickened skin on the face and an enlarged, bulbous nose (rhinophyma). People with rosacea may feel itching, stinging, or burning sensations in affected areas. Often, the disorder affects the eyes, causing abnormal inflammation of the eyelids and eyes (ocular rosacea). This inflammation can cause dryness, redness, and irritation of the eyes and may affect vision.
