The cause of rosacea is unknown, and there is no way to prevent it.

But there are steps that you can take to prevent flare-ups of rosacea, and this can help stop the condition from getting worse. You can find out what triggers your flare-ups by making a list of what you were eating or doing around the time you had a breakout. Some triggers include sun and wind, hot and cold temperatures, stress, spicy foods, skin care products, and exercise.
