If you’re looking for a gruesome looking makeup effect for your scare actors then CrazyHappy08 has a tutorial that may suit your needs. Its a super simple effect to achieve (assuming you’re reasonably adept at applying makeup) and the results look amazing. You’ll need glue, foundation, some makeup, and a bit of a depraved imagination.
