Rosacea is a chronic condition mostly affecting facial skin. It presents as chronic intermittent redness of the skin and inflammation. Rosacea is similar in appearance to acne and affects mostly fair skinned people of Northern European origin. Some know it as the “Celtic curse” because it is so common in people of Irish descent. More than 17 million individuals have some degree of rosacea in the US, and more than 45 million people are affected worldwide. Because rosacea imitates intense adult acne it is usually misdiagnosed and mistreated as acne. The parts of the body most affected are usually the face, nose, cheeks, chin and forehead. But it can appear on the neck, back and chest in some cases.
