Over 14 million Americans have rosacea. There are three types of rosacea dermatologists usually see – vascular (erythematotelangiectatic), papulopustular, and a combination. Ocular rosacea involves discomfort or grittiness in the eyes that can be treated. Rare types that are more serious are the phymatous type (with an enlarging bulb-like nose) or the granulomatous type that can leave more scarring. Most people do not realize that rosacea is a treatable condition. They often suffer embarrassment and redness on the face when dermatologists have many different treatments available.
There is also a lot of great information available at the National Rosacea Society.
