Final Seal is also a good product to lay down before putting on any makeup, especially for more sensitive skin, as it creates a barrier between the skin and the paint. Like it was said above, clean skin is very important.
I would look into Wolfe FX and Kryolan like animenerd93 suggested, and ask around local theatrical supply stores as to what the professionals use as well. Get a lot of information from various sources!
