How long after a rosacea trigger will a rosacea flare-up occur?
A. Although there are no data available on how quickly a rosacea trigger may lead to a flare-up, the time is likely to vary depending on the individual and the nature of the trigger. Try monitoring your individual case to see how quickly your rosacea has responded. And remember, while a wide range of factors has been identified as potential triggers, not every trigger affects every individual everytime.
