What is the purpose of spirit gum in special effects make-up?

Spirit gum serves a specific purpose in special effects make-up by adhering hairpieces or other materials to the skin or face. When applying wigs, beards, or additional hair for character transformation, spirit gum allows for a strong bond that helps the pieces stay in place throughout a performance or event. Its adhesive properties are particularly valued in the make-up industry because they are designed to safely adhere to skin, ensuring that the application looks natural and remains durable during use.

The other choices do not accurately represent the main function of spirit gum. Blending colors together typically involves the use of makeup products like creams, pigments, or powders. Creating shadows is achieved through techniques involving the application of darker shades or contouring products, rather than an adhesive. Finally, removing make-up requires the use of specific cleansers or solvents, which is distinctly different from what spirit gum offers as a sticking agent.
