Rosacea has commonly been characterized as a disease of flare-ups and remissions, and data from a recent National Rosacea Society survey of 954 patients confirm that pattern.

More than 55 percent of the respondents said they experience an outbreak or increased intensity of symptoms at least once a month, including 24 percent who noted they have a flare-up every few days, 15 percent who said once a week, and the remainder who said once a month. Another 25 percent said they have a flare-up every few months.
