Thanks to good ol' Preparation H, if you feel that your jawline is sagging a bit before an important meeting, get together, smear on some of the stuff. It'll tighten your jaw line. It reeks, though, that's the only snag.
You'll look younger, but you might smell as if you belong at Del Boca Vista.
It works for sagging, bagged out wrinkly eyes, too. Tightens the skin right up, you'll look years younger. Again with the smell, but if you note Pip's Perfume quiz, maybe you can drown out the smell of the Preparation H by dousing yourself with cheap dollar store garbage.
This is an old model's tip, by the way.
