ROSACEA

Rosacea is a chronic skin disorder that causes redness of the cheeks, chin, nose and forehead. Left untreated, it can lead to the development of acne-like pimples and visible blood vessels on the face. In severe cases, the skin around the nose swells and thickens, giving it a bulbous, bumpy appearance.

In approximately 60 percent of rosacea sufferers, the eyes are also affected. Signs and symptoms include swollen eyelids and bloodshot eyes that water, sting, and burn.

In spite of ongoing research, the exact cause of rosacea remains unknown. At one time or another, scientists have speculated that the condition might be caused by bacteria, skin mites, fungus, or a malfunction of the blood vessels underlying the skin, but so far, none of these theories has been proven.

There's some evidence to suggest that heredity could play a role. Many rosacea sufferers may have at least one relative with similar skin problems. People of European descent appear to be especially susceptible to the condition.

Rosacea is more common in women, but it tends to be more severe in men. While the condition may strike in the teens or early twenties, it's far more likely to occur later in life.
