| Alternative Names | Acne rosacea |
| Causes, incidence, and risk factors | The cause of rosacea is unknown. The disorder involves enlargement of the blood vessels just under the skin. It occurs most often in fair skinned people, particularly those who blush easily. Women are more commonly affected, but men are usually more severely affected. Symptoms usually begin between ages 30 to 50. Rosacea may be associated with other skin disorders ( acne vulgaris , seborrhea ) or eye disorders ( blepharitis , keratitis ). |
| Symptoms | rasheserythema (red areas on the face) discrete areas or the entire face a tendency to flush, blush easily increased vascularity (telangiectasis) of the face a red, bulbous noseacne-like skin eruptions ( macules , nodules , pustules , may ooze or crust) a burning or stinging sensation of the face |
| Signs and tests | Your physician can usually diagnose rosacea with a thorough medical history and physical exam. |
| Treatment | There is no cure known for rosacea. The treatment is aimed at the control of redness, inflammation, and skin eruptions. Long-term treatment (5 to 8 weeks or more) with oral antibiotics such as tetracycline may control skin eruptions. Oral medications similar to Vitamin A (isoretinol or Accutane) are a stronger alternative. The treatment of skin eruptions may also include long-term treatment with topical (applied to a localized area of the skin) antibiotics such as metronidazole. In severe cases, laser surgery may help reduce the redness. Surgical reduction of the nose hyperplasia may also improve the patient's cosmetic appearance. |
