Rosacea is a chronic skin condition resulting in facial redness and inflammation. It may appear as redness, prominent spider-like blood vessels, swelling, or skin eruptions.
Wikipedia says that unless it affects the eyes it is usually a harmless condition, and that if topical steroids are used to treat it - it can aggravate the condition. It usually affects caucasians, is most common in women, and usually appears between ages 30-60.
Cathelicidin (a peptide, or enzyme), intestinal bacteria, certain skin mites, temperature extremes, and facial flushing from heat, exercise, stress, cold wind, and some foods and drinks may be contributing causes.
Wikipedia indicates that medications such as oral and topical antibiotics are a first line of defense. In addition, broad spectrum light treatment may be very effective.
