I've not yet seen mineralize products faked nor most foundations. The foundations that I have seen reasonably accurately faked tend to be Lightful and Pro Preferred White products which were really only big in Asian markets. As most of the fakes are made in Thailand or China, this makes sense.
I've also not seen concealers, eye lashes, primers or skin care products yet
I have seen counterfeit eye shadows, mascara, blushes, powders (compact and loose), lipsticks, lip pencils, eye pencils, liquid eye liners, some foundations (as mentioned above), liplosses and lipglasses, brushes and pigments/glitters.
