Where is the mentalis muscle located in the face?

Normally, the mentalis muscle is located in the anterior part of the mandible in the face and is one of the facial expression muscles. If discomfort occurs, it is recommended to seek medical attention promptly. Specific analysis is as follows:

The mentalis muscle originates from the front portion of the mandible and attaches to the skin and soft tissues of the lower jaw. It is a relatively small muscle composed primarily of muscle fiber bundles that can elevate and tighten the skin and soft tissues of the chin area, thereby creating a firmer and more defined jawline. Additionally, contraction of the mentalis muscle helps maintain stability of the oral cavity and larynx, and plays a role in expressing emotions such as doubt, anger, and contempt.

In daily life, it is advisable to maintain proper posture, ensuring the head and neck remain naturally upright, avoiding prolonged periods of looking down or excessive head tilting, to reduce strain on the mentalis muscle. At the same time, appropriate facial massage may help promote blood circulation and improve the firmness and elasticity of the mentalis muscle.
