We estimated the global prevalence of rosacea based on published data and found that 5·46% of the adult population is affected. However, the prevalence of rosacea depended on the diagnostic method, with higher estimates in questionnaire studies of rosacea symptoms and lower estimates in health registries with International Classification of Diseases codes.
