Try Clinique as well. They are known for their hypoallergenic products. I don't have any allergies to any foundations, but I like to put a little liquid foundation on the areas with the most needs and then brush mineral foundation over the whole face. I really do like the look of the mineral foundations.
You really need to try a bunch of different products. Also, check out some less expensive product lines which are hypoallergenic. I'm sure there are some, I just don't know for sure about them.
