We know that inflammation is at the heart of the problem with rosacea, but we don’t know exactly what triggers it. Some triggers include stress, sun exposure, weather, alcohol, hormones, spicy foods, heavy exercise, hot tubs, fragrances, allergies, and so on. It may also be a combination. You’ll start to learn what your individual triggers are, and then you can try your best to avoid them. Stress is a biggie, so do what you can to keep your stress in check. Since symptoms as well as triggers can vary considerably from person to person, knowing what activates your rosacea is step one in preventing and controlling it. For instance, some people with rosacea can tolerate Retin-A and/or glycolics. There is no cure for rosacea, but there are treatments aimed at decreasing redness, inflammation and acne bumps. No sugar and no caffeine isn't a proven method, but again, if you think those are your triggers, then try to go without. It's best to follow a routine like this for three months to see if it helps. If it doesn't make a difference then see a dermatologist who can help with a new treatment plan.
