There are many possible causes for rosacea, some of which are easier to avoid than others. Simple lifestyle tweaks like cutting down on hot drinks, spicy foods, red wine and other types of alcohol can make a big difference, whereas other causes are not so easy to navigate. Environmental conditions like sunlight, wind, and extreme temperatures can cause rosacea to flare up, and depending on where you live, these things may be difficult to avoid. Other things that can cause rosacea to flare up include exercise, intense emotions, and certain drugs and cosmetic products. You are particularly prone to rosacea if you are a female over 30 with light skin. Likewise, if you smoke or have a family history of the condition.
