Doctors can describe the symptoms of rosacea, a common inflammatory skin disease that causes facial redness and affects nearly 14 million Americans. They can tell patients what triggers can worsen their condition: spicy foods, heat, alcohol, even embarrassment. But until now, they could not explain what caused rosacea.A team of researchers, led by Richard L. Gallo, M.D., Ph.D., professor of medicine and chief of the Division of Dermatology at the University of California, San Diego (UCSD) School of Medicine and the Dermatology section of the Veterans Affairs San Diego Healthcare System, has determined that it is not one, but a combination of two abnormal factors, that result in rosacea.
