Rosacea 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. The cause of rosacea is unknown, but it could be due to an overactive immune system, heredity, environmental factors or a combination of these.
- 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.
