Rick in WI: I've suffered from Rosacea for over 20 years and have tried many things. I have found that there is several foods that trigger my redness and they are citrus (like oranges and lemons) and raisins. I have just recently started using a sunscreen that has "clear zinc oxide" ing the sun screen and with it have seen a great improvement. I have purchased the clear zinc oxide at a local pharmacy and paid less then 5.00. I apply it every morning before going out for the day.
