metaphorically refers to the human body or specific areas of the body undergoing procedures or treatments; the medium through which practitioners work, employing controlled introductions of trauma, such as surgical incisions, injections, or noninvasive body contouring, to sculpt, reshape, or enhance the body’s appearance or features according to the client’s desired aesthetic outcomes. The term “canvas” in this context signifies the malleability or modifiability of the body as an artistic or transformative medium for aesthetic interventions.
