10 minutes
No lipstick
Camera angle zoomed very close to your mouth and part of your nose like the screenshot.

You're just pushing your lips into a square over and over, facing center the entire time.

With some squares when you're in the square shape, you can raise your upper lip like you're selling your lip while your lips are still in the square shape.

Last 30 seconds - Camera zoomed out very slightly to show all of your face very very close, filling the entire screen as you square some more.
