Chin Muscle

The chin muscle forms a bulge in the chin area and is a bundle of muscle fibers assembled in the shape of a cone. 👩‍🎓
This muscle originates on the lower jaw and the other end is woven into the skin of the chin.
Contracting, the chin muscle tightens the skin of the chin and protrudes the lower lip.
Accordingly, working with this muscle can help in correcting the shape of the lower lip.
