For EVERYDAY MINERALS? Like, for blushes, there are different types of finishes, like matte and lucent, what does what?
As for concealers, they have some like blue or green or yellow kinds of concealers, what do the different colors do?

((Mainly wondering about the blues, pinks, and greens!!))

I heard something about the blush oxidizing, though I don’t know what this means.

I don’t know if it has anything to do with quality because one of my Estee Lauder blushes does the same thing.
