Prosthetic makeup is the process of using prosthetic sculpting, molding and casting techniques to create advanced cosmetic effects. The process of creating a prosthetic appliance begins with lifecasting, the process of taking a mold of a body part (often the face) to use as a base for sculpting the prosthetic. Lifecast molds are made from prosthetic alginate or more recently, from skin-safe silicone rubber. This initial mold is relatively weak and flexible. A hard mother mold, typically made of plaster or fiberglass bandages is created overtop the initial mold to provide support.
