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.

NIH: National Institute of Arthritis and Musculoskeletal and Skin Diseases

Definition (NCI) A chronic erythematous skin disorder that affects the face. It is characterized by the development of redness in the cheeks, nose, and/or forehead and telangiectasia. Sometimes, the erythematous changes may involve the eyelids.
Definition (MSH) A cutaneous disorder primarily of convexities of the central part of the FACE, such as FOREHEAD; CHEEK; NOSE; and CHIN. It is characterized by FLUSHING; ERYTHEMA; EDEMA; RHINOPHYMA; papules; and ocular symptoms. It may occur at any age but typically after age 30. There are various subtypes of rosacea: erythematotelangiectatic, papulopustular, phymatous, and ocular (National Rosacea Society's Expert Committee on the Classification and Staging of Rosacea, J Am Acad Dermatol 2002; 46:584-7).
