Take your skeleton makeup to the next level when you try out this creepy look. You'll need to apply skin glue to the area above your lips, on your chin, and on parts of your cheeks. Then, apply cotton coil in the shape of a large smile. Add red face paint to the area in between the smile, and then add thin strips of cotton coil to the top and bottom of the smile outline. Apply a coat of foundation to the cotton coil and blend it into your skin so your face and the cotton are the same colour. Add fake blood to the skeleton smile as well as to parts of your cheeks and nose, and you'll be a chilling sight for all to see.
