DEAR DOCTOR K: I read your column on adult acne with great interest. For years, I thought I had adult acne, but when I finally saw a doctor, she diagnosed me with rosacea. I'd like to learn more about this condition.
DEAR READER: Rosacea is a long-lasting skin condition that causes inflammation and redness of the face. Remember the comic W.C. Fields — and what his nose looked like? He had rosacea. Rosacea tends to begin in adults over the age of 30, although it can affect younger adults and kids. Rosacea is sometimes confused with acne, but acne usually starts in childhood and affects more of the skin of the face than rosacea does. Rosacea also has different causes than acne.
