Its possible to get a reaction to something you have used for a long time, and its also possible they changed the formula of something.
I'd try dabbing each product on the inside of my elbow for a couple of days and see if its just one thats making you break out. You could also read teh ingredients and find another brand that doesn't have those ingredients.
I have fairly sensitive skin and get hives from a lot of stuff but I can use the mineral powder makeup on my face without an issue, you might try that kind. I use Bare Minerals that I buy at an Ulta store but theres a lot of brands.
