The facial muscles are just under the skin (subcutaneous) muscles that control facial expression. They generally originate from the surface of the skull bone (rarely the fascia), and insert on the skin of the face. When they contract, the skin moves. These muscles also cause wrinkles at right angles to the muscles’ action line.

The corrugator supercilii muscle is a small, [1] narrow, [citation needed] pyramidal muscle [1] of the face. [citation needed] It arises from the medial end of the superciliary arch; it inserts into the deep surface of the skin of the eyebrow. It draws the eyebrow downward and medially, producing the vertical "frowning" wrinkles of the forehead.
The frontalis muscle is thin, of a quadrilateral form, and intimately adherent to the superficial fascia. It is broader than the occipitalis and its fibers are longer and paler in color. It is located on the front of the head. The muscle has no bony attachments. Its medial fibers are continuous with those of the procerus; its intermediate ...
Mentalis. Muscles of the head, face, and neck. The mentalis muscle is a paired central muscle of the lower lip, situated at the tip of the chin. [ 1 ] It originates from the mentum of the mandible, and inserts into the soft tissue of the chin. It is sometimes referred to as the "pouting muscle" (as in duck face )due to it raising the lower lip ...
9624. Anatomical terms of muscle. [edit on Wikidata] The occipitofrontalis muscle (epicranius muscle) is a muscle which covers parts of the skull. It consists of two parts or bellies: the occipital belly, near the occipital bone, and the frontal belly, near the frontal bone. It is supplied by the supraorbital artery, the supratrochlear artery ...
The zygomaticus major muscle is a muscle of the face. It arises from either zygomatic arch (cheekbone); it inserts at the corner of the mouth. It is innervated by branches of the facial nerve (cranial nerve VII). It is a muscle of facial expression, which draws the angle of the mouth superiorly and posteriorly to allow one to smile.
Depressor anguli oris muscle. Scheme showing arrangement of fibers of Orbicularis oris (triangularis labeled at bottom right). Muscles of the head, face, and neck (labeled as triangularis near chin). The depressor anguli oris muscle (triangularis muscle) is a facial muscle. It originates from the mandible and inserts into the angle of the mouth.
