What you’ll need
We will use 1:1 ratio for our flour and Vaseline mixture
Now mix together until it turns into a dough like texture
Mixture should look similar to this
Now use a small piece of silicone mixture and spread! (Take your time doing this part)
Now carve in whatever design or “cut” you want! Tip: add foundation over silicone to look more real
Go in with some fake blood, and wala!
Scar will look much better w/ foundation to blend into natural arms color, & shadows for “bruising”
This is what my silicone looks like when I go over it with some makeup and liquid latex!
