I use both concealer and foundation. Concealer goes under my eyes and on any areas I want to even out, usually my cheeks. It's thicker than foundation, and more solid, if that makes sense. My liquid foundation is runny, but the foundation is firmer, doesn't run. I don't use mineral foundation because, for my skin, it doesn't look the best. I do have mineral powder, but probably not the way most people do. It's not powder foundation, it's just..powder. I use a duo fibre brush to buff it on my skin, over my foundation.
