Men and women of all ages can be affected, with an estimated 45 million sufferers worldwide. The Rosacea Research & Development Institute is a non-profit corporation founded and run by volunteer rosaceans, as a patient advocacy organization and to promote rosacea research. The goal of the RRDi is to contribute to the development of improved treatments for rosacea, and ideally, to help find a cure.view less
