Its primary function is to draw the eyebrows downward and together, which creates the expression often associated with frowning or concentration. This action is important in nonverbal communication, as it conveys emotions such as concern or irritation.

Understanding the specific role of this muscle is critical in esthetics, particularly in facial treatments and when considering how different facial expressions can be affected by various procedures. It highlights the intricacies of facial anatomy and the importance of recognizing how changes in the muscles can influence appearance and expression.
