Rosacea is a relatively common, chronic skin disorder believed to affect 14 million Americans. Its classic symptoms are patchy flushing (redness) and inflammation, particularly on the cheeks, nose, forehead, and chin. It typically appears between the ages of 30 and 50 and affects more women than men. Because the symptoms emerge slowly, rosacea may be mistaken at first for sunburn, leading to a delay in treatment

As the condition progresses, flushing becomes more persistent and noticeable. Some people also notice stinging or burning sensations in the affected areas. Small, red, solid bumps (called papules) and pus-filled pimples (called pustules) may appear on the skin. Because these appear similar to acne, the condition is sometimes mistaken for acne itself.

Small, dilated blood vessels (telangiectasias) may become visible, too. Often, when people with rosacea blush, the enlarged blood vessels in their faces look like thin red lines. In some cases, the eyes also may become involved -- and may become red, irritated, and may burn (ocular rosacea).

In advanced cases, more of the face is affected. The skin swells, cysts form, and small, knobby bumps develop on the nose, making it appear red and swollen. This condition, called rhinophyma, is relatively uncommon and primarily affects men. It was the cause of the late comedian W.C. Fields' best-known feature -- his trademark bulbous nose.

Rosacea may be persistent and worsen over time, leading to permanent changes in appearance and affecting self-esteem. There is no known cure for rosacea, but the condition is treatable. Most cases can be controlled by avoiding factors that trigger flushing such as sun exposure, spicy foods, drinking hot beverages and alcohol, using sun protection, and by using medication.
