No one knows the cause of rosacea. There may not be just one cause. Rosacea tends to run in fair-skinned families and tends to occur in people who blush easily. Symptoms usually begin in adults between the ages of 30 and 50. Women are more likely to get rhinophyma.
Rosacea tends to be more severe in men.
No, but it can be treated. Rosacea is a condition that lasts for a long period of time. Rosacea may get worse over time if it is not treated. Treatment is aimed at controlling the symptoms and making your skin look better. The type of medicine your doctor recommends will depend on how your skin looks.
