How to Treating Rosacea One of the most difficult things to treat is a disease with an unknown cause. Not knowing where the problem comes from makes giving medications dangerous. Rosacea is such a disease. Even with tens of millions of people affected by the skin problem, scientists still do not know what exactly causes it. What makes rosacea so unique is the fact that flare ups are triggered by a host of factors and not all people have the same set of triggers. The irregularity of its cause and even the occurrence of its symptoms make this skin problem harder to detect and harder to treat. Those with only mild symptoms can just simply avoid contact with their triggers, provided that they do know what their triggers are. Sun exposure and changing weather are the most common triggers along with spicy food and stress. Some vegetables like eggplants and spinach can also trigger breakouts. Also citrus fruits, raisins and plum. Chocolates and other dairy products are also in the list of triggers. Also cigarettes and alcoholic beverages.
