Final answer:
To make a character appear aged, shading the nasolabial folds, applying foam latex prosthetic appliances, and using greasepaint can be used.
Step-by-step explanation:
To make a character appear aged in theater, film, or television productions, one method is to shade the nasolabial folds. These are the lines that run from the corners of the nose to the corners of the mouth, and adding shadow can create the appearance of wrinkles. Another method is to apply foam latex prosthetic appliances, which are pre-made pieces that can be attached to the actor's face to simulate aging features. Lastly, applying greasepaint can be used to create wrinkles, lines, and other signs of aging on the skin.
