Sherri, I have rosacea, too, and like Terra mentioned, a good moisturizer/skin tone evener is really what helped me more than finding the right make up (which I don't wear often at all). In the past, the best I've ever used is Estee Lauder Idealist Even
Skintone Illuminator. It's pricey, but that little bit does go a long way. I'd love to find something that has the same effect but cheaper, though.
