When you're contouring, you want to make sure that whatever you use is a matte color. Anything with shimmer will just bring attention to the area when the point of contouring is to add shadows. I've used bronzers before but sometimes they're too light for contouring since my tan is permanent haha. Powdered foundation is probably my favorite thing to use since it's usually matte and comes in a variety of shades.
I don't know if you have it in your country but L'Oreal True Match Powder Foundation is a great powder for oily skin (I have oily skin too and it's my favorite everyday foundation) and has absolutely no sparkle in it.
What's this for? It's a wig.
What's it for? To disguise yourself from yourself.
