A life mask is a mold or cast of an individual's face or head, usually made for artistic or scientific purposes. While this term is commonly used, there are several other words that can be used synonymously with it. For instance, a death mask is similar to a life mask but is made after the person's death. A bust, on the other hand, refers to a sculpture of a person's upper body, usually from the shoulders upwards. And if someone has a portrait of their head, it can be called a likeness. So, whether you're looking to create a detailed imitation of someone's features or add to your vocabulary, these synonyms for life mask can come in handy.
