Prosthetics are artificial body parts or facial features used in special-effects makeup or as theater costume accessories. Prosthetics makeup is made with silicone and is designed to replicate realistic features, wounds, scars, and more by adhering to the skin. Prosthetics are great tools when altering actors’ or models’ facial features for film, television, or photography, and can also be useful for those looking to change their appearance for a themed party or Halloween event.
