Rosacea is a skin disease that causes redness and swelling of the face. As the disease progresses, small vessels and tiny pimples begin to appear on and around the reddened area.
In advanced cases, the disease can be characterized by a enlarged red nose and puffy cheeks. Approximately half of all rosacea patients experience burning and grittiness of the eyes—a condition commonly known as conjunctivitis, which should be treated immediately.
Rosacea is treated with various topical and oral medications. Severe cases may be treated with lasers or intense pulsed light therapy.
