Dab a little on the outer/lower side of your cheekbone and then blend to use as a quick effective substitute for blush.
I'd heard of this idea many years ago but it sounded so preposterous that I never gave it much consideration until I saw a friend using is. She dabbed red lipstick around the goatee area of the face and then rubbed it even with her fingers. Then foundation was applied as usual. She explained the concept is that instead of a dark shadow eventually showing through the foundation, a hint of the lipstick will show which looks much more like pink flesh than beard.
