DwDIQ, check out the thread on Bare Minerals and Lynn's brand (also in this category) and there is more about mineral foundations in the comments on this topic of MK Sucks:
http://marykaysucks.wordpress.com/2006/10/10/another-reformulated-mary-kay-product/ (I think they start around comment #55). I have seriously combination skin that is also very sensitive. I have dry patches but also get so oily that I used to have to reapply my makeup in the afternoon. The oil mattified from MK really helped, but I have also noticed a huge improvement with the mineral foundations. They blend better, they look more natural, and they don't rub off on my clothes and my cell phone!
I also have acne flair-ups and the mineral foundations covers it nicely and doesn't seem to settle on it like the liquid from MK did. I LOVE the mineral foundations and can't imagine ever using anything else ever again.
The Bare Minerals isn't cheap, but it's worth it, and it lasts a long time. Check into Lynn's brand too (Beauty Bliss Mineral Cosmetics) and you can get really cheap samples to make sure your colors are right and her full-sized containers are less than the BM too.
