Well about the Benefit stuff. It´s called a "Foundation Faker" and it´s in a compact case. It´s supposed to be one shade suits all (as it has little actual coverage). It goes on creamy, which feels kinda weird at first, but then dries to a powdery finish. Your skin feels silky smooth with it on.
I like to wear it on top of mineral foundation because my skin is not great enough to get away with the Benefit stuff by itself. I do believe Some Kind-a Gorgeous makes my pores appear smaller and also helps to make the mineral foundation look smoother, more airbrushed.
The downside: I read it´s only really suitable for medium skintones. So if you´re super pale or super dark, it might not be for you
