I put it on everyday as part of my morning routine after I shower. The only real exception to that would be if I was staying home sick and not leaving the house.
I wear a very minimal amount of makeup though (powder, blush, mascara, sometimes lip gloss) and it is very natural looking. It takes me about 3 minutes tops for my makeup routine. I only use things like foundation, lipstick, or eyeshadow on special ocassions.
