What Increases Your Risk
There are no known risk factors for rosacea. But many people with this skin condition have family members with rosacea. 1
Certain triggers can cause flushing of the skin and a flare-up of rosacea symptoms. These triggers include sun, stress, hot weather, alcohol, caffeine, spicy food, exercise, hot baths, and cold weather. Triggers produce a sudden increase in blood flow through the blood vessels in the face. This causes the blood vessels to expand and the face to flush. A trigger that affects one person may not affect another.
