Step 1: What You Need:
Trauma Stack Makeup
Flesh Stack Makeup
Sculpey or similar modeling clay
A toothpick or similar, I used a Flosspick
Step 2: Form the Form
Once you get the shape good, carefully use the toothpick to pull it off the table.
Step 3: Apply the Form
1. Arm hair interferes with flesh latex application
2. It will hurt like balls when you tear the spirit gum off
So, turn the Form over and brush spirit gun all over the bottom. Lightly tap the wet spirit gum until it is sticky, known as "tacking". Then, apply it to your skin. Be sure to get the edges of the Form to blend as evenly with your skin as possible.
Step 4: Conceal Edges
Apply generous amounts of the latex around the edges, the tap it gently to smooth out the bumps.
While you are waiting for the latex to dry, put some notches and grooves in the Form with the toothpick (or Flosspick), to give the blood gel "channels" to run in.
Step 5: Add bruise
Then, use a q-tip to rub it into an even bruise color
