According to a new study, rosacea is the most common facial skin disorder overlapping with seborrheic dermatitis (SD), a chronic and recurring inflammatory condition characterized by a red, scaly or itchy rash often found in the creases around the nose, the inner eyebrows or as dandruff on the scalp. Dr. James Del Rosso, clinical assistant professor of dermatology at the University of Nevada, found that 26 percent of rosacea patients had facial SD and 28 percent had SD of the scalp.1
