Rosacea is a skin condition that causes redness and tiny, red bumps on the face. It is estimated to affect at least 16 million people in the U.S, most of whom are Caucasian with fair skin. The condition commonly affects the central third of the face, especially the nose, and has periodic ups and downs (flares and remissions). People typically equate rosacea with having a red, flushed face, but for most sufferers, the symptoms go beyond this and can include “spider veins” (visible broken blood vessels); swollen and painful skin; bloodshot eyes; sensitive skin that easily reacts to the sun, skin care products, heat or sweat; stinging or burning skin; and rough, itchy or scaling skin. The underlying causes of rosacea are still relatively unknown, but some experts now believe that rosacea is caused by demodex mites.189 Common rosacea triggers can include alcohol, hot or spicy foods, emotional stress and heat.
