I practically never contour (or wear makeup at all tbh because I'm lazy AF and choose the extra 20-30 minutes of sleep), but just think of it like you're coloring one of your panels!
also, idk what your technique is but dabbing the makeup on an sort of pressing it into the skin vs smearing it on was a gamechanger for me. Like holy crap it was amazing why did no one teach me this before
I personally don't wear foundation etc bc I am just not good at it and I look terrible with it
