The redness and flushing associated with rosacea is thought to be due to increased numbers of blood vessels close to the skin's surface. These blood vessels may dilate more often or more dramatically in people with rosacea, leading to increased blood flow to facial skin. The cause of these vessel problems is unknown, but there are theories that it may be due to an immune response to mites or bacteria on the skin, or may even be related to the amount and type of gastrointestinal bacteria.

Rosacea is more common in people ages 30-60, in women, in people with fair skin and for those with a family history of the condition.

There is no specific test for rosacea, so your doctor will usually diagnose it based on your symptoms and the appearance of your skin.

While rosacea can't be cured, some treatments may help control symptoms and reduce redness.
