You don’t want people to say your makeup looks like a clown’s, but you do want it to stay on like one.
Let me explain.
Dermacolor Fixier Spray has been used for years to set the makeup of professional clowns who need their makeup to stay on so they can properly scare the life out of children (and me.) I guess the only thing worse than a clown in full, pristine makeup is one with it smudging down his face a’la Heath Ledger in Dark Knight. It’s on my wish list to pick up so I can’t vouch for it, but if it’s good enough for the scary guys in the Volkswagen, it’s good enough for me.
