I’ve been a professional makeup artist for almost 20 years. However, my mainstream had been beauty and recently started doing Special FX. As per another pro’s recommendation, I used Mehron’s SynWax for these bullet holes and to create a chopped-off finger effect. I’m beyond satisfied. Please make sure to use little Vaseline (not too much, or it won’t stick to the skin) to knead the amount you will use and set it with translucent (colorless) or talcum powder. You can also knead-in foundation to make the prosthetic darker. It works best on bare skin but, in a pinch, you can make a small prosthetic to adhere to skin that already has foundation and powder (eg: my forehead bullet hole). This is an excellent and versatile product.
