What is the name of the muscle that extends from the upper part of the shoulder to the corner of the mouth that is massaged during a facial?

The muscle that extends from the upper part of the shoulder to the corner of the mouth is the platysma. This superficial muscle is situated in the neck and lower face, and it plays a significant role in facial expressions, particularly in conveying emotions such as sadness or surprise. During a facial treatment, the platysma is often massaged to promote relaxation, improve circulation, and enhance the overall appearance of the skin.

The positioning of the platysma allows for its engagement during various facial movements, and it's directly involved in the aesthetic outcome of a facial, making it a focus during massage techniques in aesthetical practice. Understanding the anatomy of facial muscles like the platysma helps practitioners enhance their techniques and provide better care to clients seeking facial treatments.
