Picture of Rosacea 1
Rosacea (say "roh-ZAY-sha") is a skin disease that causes redness and pimples on your nose, cheeks, chin, and forehead. The redness may come and go. People sometimes call rosacea "adult acne" because it can cause outbreaks that look like acne. It can also cause burning and soreness in the eyes and eyelids.
Rosacea often flares when something causes the blood vessels in the face to expand, which causes redness. Things that cause a flare-up are called triggers. Common triggers are exercise, sun and wind exposure, hot weather, stress, spicy foods, alcohol, and hot baths. Swings in temperature from hot to cold or cold to hot can also cause a flare-up of rosacea.Rosacea can be embarrassing. And if it is untreated, it can get worse. If the symptoms bother you, see your doctor and learn ways to control rosacea.
