Two recent studies, funded by individual donations to the National Rosacea Society (NRS), have discovered potential key factors in the development of rosacea that open new possibilities for important advances in its treatment and prevention.

A malfunction in part of the body's nervous system may be linked to the redness as well as the bumps and pimples of rosacea, according to a recently completed study by Dr. Akihiko Ikoma and colleagues at the University of California-San Francisco.
