Rosacea results from dilation of small facial blood vessels; the cause of this dilation is

Overview

Rosacea (roe-ZAY-she-uh) is a common skin condition that causes blushing or flushing and visible blood vessels in your face. It may also produce small, pus-filled bumps. These signs and symptoms may flare up for weeks to months and then go away for a while. Rosacea can be mistaken for acne, other skin problems or natural ruddiness.

Rosacea can affect anyone. But it's most common in middle-aged white women. There's no cure for rosacea, but treatment can control and reduce the signs and symptoms.

Symptoms

Signs and symptoms of rosacea include:

  • Facial blushing or flushing. Rosacea can cause a persistent blushing or flushing in the central part of your face. This sign of the condition may be difficult to see on brown and Black skin.
  • Visible veins. Small blood vessels of your nose and cheeks break and become visible (spider veins).
  • Swollen bumps. Many people with rosacea also develop pimples on their face that resemble acne. These bumps sometimes contain pus.
  • Burning sensation. The skin of the affected area may feel hot and tender.
  • Eye problems. Many people with rosacea also experience dry, irritated, swollen eyes and eyelids. This is known as ocular rosacea. In some people, the eye symptoms precede the skin symptoms.
  • Enlarged nose. Over time, rosacea can thicken the skin on the nose, causing the nose to appear bulbous (rhinophyma). This occurs more often in men than in women.

When to see a doctor

If you experience persistent symptoms of your face or eyes, see your doctor or a skin specialist (dermatologist) for a diagnosis and proper treatment.

Flare-ups might be triggered by:

  • Hot drinks and spicy foods
  • Red wine and other alcoholic beverages
  • Temperature extremes
  • Sun or wind
  • Emotions
  • Exercise
  • Drugs that dilate blood vessels, including some blood pressure medications
  • Some cosmetic, skin or hair care products

Risk factors

Anyone can develop rosacea. But you may be more likely to develop it if you:

  • Are female
  • Have skin that burns easily in the sun
  • Are over age 30
  • Smoke
  • Have a family history of rosacea
