The iris of your eye (the colored part) is a muscle that controls the size of the pupil (the black part that let’s light in). The muscles in your cheeks control the corners of your mouth, which I guess is why they’re all sunk in: no tension to hold the skin up.
I’m not so sure about the accuracy of this picture either, maybe it was something else with a funny caption?

They are not just sunken in. We see the teeth, there is nothing left. As if they are made of 100 % muscle.
