This moulage is of a fresh frostbite injury.
The basic tools are Ben Nye white creme make-up and black eye shadow. You don't have to use the black eye shadow, but it hides the imperfections around the edge of the fingernail and simulates dirty fingers.
You can also use this effect on the tip of the nose, the ears, cheek bones and the toes. As always. it's a good idea to coat the manikins skin with Vaseline prior to applying make-up. Also, test the product in an obscure area or on a piece of old skin before using on the manikin. This is a good reason not to discard old skins when you replace them.
