I actually put a light moisturizing lotion with SPF 15 on my face first. I then use an under-eye cream, and use the Too Faced primer mostly on the bridge of my nose and cheeks, with some on my forehead and chin. I then put on a light layer of foundation, as the primer helps the foundation "stick" to your face. I then finish off the foundation with a light layer of powder, which I apply with an oversized, soft-bristle kabuki brush. So technically I use all of the above in the above order!
