 An investigator-blinded, prospective, 6 month study of subjects with persistent erythema associated with active rosacea will be conducted in 20 subjects aged 18 years and older. All subjects will receive standard-of-care brimonidine topical gel, 0.33 with instructions to apply it once daily per package insert. Adherence will be assessed using weekly internet surveys to document how often the medication is being used, as well as reminders about rosacea triggers and general use of brimonidine.
