Which muscle is located above the upper lip and helps to express distaste?

The muscle located above the upper lip that aids in expressing distaste is the quadratus labii superioris. This muscle is part of the facial muscles involved in facial expressions. Specifically, when it contracts, it elevates both the upper lip and the corners of the mouth, which can create a facial expression associated with disdain or dislike.

In the context of esthetics and facial anatomy, understanding the function and location of this muscle can be particularly useful for professionals who perform treatments or exercises that involve facial aesthetics. The quadratus labii superioris plays a critical role in how an individual expresses emotions through facial movements, making it essential knowledge for anyone in the field of esthetics.
