They always say that two heads are better than one!

In this creepy makeup tutorial, Youtuber Promise Phan shows you how to create ‘Face In A Face’. This is the perfect way to scare your friends on Halloween!

Who knew a little marker could turn a beautiful face into a horrific image beyond our wildest nightmares? Okay, well maybe that's a bit of an exaggeration, but there is something eerily hard to shake about Sebastian Bieniek's "DoubleFace" series, which explores the age old question of what you would look like if you were quite literally two-faced.

The images, which hinge on the model's real eye and take off from there, remind us of what a Picasso painting might look like in real life. Which means we sincerely hope no Picasso painting ever, ever comes to life.
