Phases and Symptoms

Pre-rosacea is marked by redness in the middle of the face, which results from dilated blood vessels near the surface of the skin. This progresses to vascular rosacea, where blood vessels on the cheeks and nose become evident. Inflammatory rosacea---the last stage---presents itself as redness in the middle of the face accompanied by small red pimples that might appear on the nose, cheeks, chin and forehead.

Cause

The medical community has not determined the cause of this condition, but it is believed that it develops as a result of a mix of genetic and environmental factors, according to the Mayo Clinic.

Risk Factors

You are more likely to develop rosacea if you are light-skinned, between the ages of 30 and 60, tend to blush or flush often, or have a family history of the condition.

Complications

The only complication from rosacea is rhinophyma, which is rare. It is marked by a buildup of excess tissue around the nose, making it appear bulbous, as a result of enlarged oil glands in that area.

Treatment

Treatments include oral and topical antibiotics, topical treatments containing sulfur, azelaic acid, tretinoin and Accutane. In the case of rhinopyma, laser surgery is often prescribed. Those suffering from rosacea should also avoid triggers such as spicy food and limit excessive sweating, as well as use gentle facial products without alcohol or harsh ingredients, wear sunscreen and protect their face from the cold.
