I don't know about clearing it up, but mineral foundation is fantastic. I have sensitive skin with rosacea and it is just wonderful! Check out everydayminerals.com...they have a sample kit where you can try three shades of foundation, as well as some other things and all you have to do is pay a couple of dollars for shipping...well worth it and it's a great product. Plus, it won't be 'obvious' makeup, either.
