Rosacea is a long-term disease that affects your skin and sometimes your eyes. It causes redness and pimples. Rosacea is most common in women and people with fair skin. It most often affects middle-aged and older adults.
In most cases, rosacea only affects the face. Symptoms can include
Frequent redness of the face, or flushing
Small, red lines under the skin
Acne
A swollen nose
Thick skin, usually on the forehead, chin, and cheeks
Red, dry, itchy eyes and sometimes vision problems
No one knows what causes rosacea. You may be more likely to have it if you blush a lot or if rosacea runs in your family. Rosacea is not dangerous. There is no cure, but treatments can help. They include medicines and sometimes surgery.
