It often begins as a redness that looks like a blush across the nose, cheeks, chin or forehead. As time goes on, red pimples and pus-filled bumps may appear.
Some people also notice small blood vessels across their nose and cheeks.
In some people, the skin of the nose may become red and thick. Rosacea can also affect the eyes. It may irritate and inflame the eyelids and the white part of the eye. This is called conjunctivitis. No one knows the cause of rosacea.
