Rosacea, or adult acne, is a chronic inflammatory condition of the skin on the face and the neck, usually most prominent on the central face. The cause is unknown and there is no cure. Rosacea is more commonly found in people with a fair complexion, but can be a problem in people of all ethnic backgrounds. There are certain things, called trigger factors, which can flare or worsen rosacea. These trigger factors include alcohol, stress, extreme temperatures, spicy or warm foods, hot drinks, wind, sunlight, and exercise. Rosacea affects every patient differently. Not all trigger factors are a problem for every rosacea patient, and it is not always possible to avoid these trigger factors. Patients must make an effort to use their medication daily and avoid trigger factors as much as possible.
