Causes of Rosacea

The cause of rosacea is unclear, and there may be more than one cause. Tiny blood vessels under the skin of the face enlarge and dilate. These blood vessels may become hyper- sensitive to certain triggers.

It is believed that some people have a genetic predisposition to developing it as tends to run in families.

Although treated with antibiotics, bacteria have not been proved to cause rosacea. Immune reactions in the skin may be involved. Women are more likely to get rosacea generally on the face, but men are more likely to get rhinophyma.
