Facial expression muscles contract to make facial expressions such as smiling, frowning, and squinting and so on. At the same time, they fold the skin and create wrinkles on the skin. These lines will disappear when the muscles are relaxed. If these muscles are constantly contracting, the wrinkles will stay. With age, skin cells change as well to contribute to the wrinkle formation. For example, with age the skin loses its ability to hold on moisture, makes less oil and has less ability to repair any damage. This all contributes to the wrinkle formation in some stages. Exposure to the sun too much damages the skin and produces wrinkles.
Wrinkles on the forehead are very common.
The frontalis muscle (frontal belly) is the muscle on the forehead. It is a thin, quadrilateral form. There is a pair of them. They lift eyebrows when looking up and wrinkle the forehead by pulling the scalp back.
Crow feet wrinkles at the corner of eyes.
The orbicularis oculi muscle is the ring like muscle surrounding the eye. Contraction of the muscle also causes the wrinkles at the out corner of the eye which are called crow feet. For example, as under the sun, the skin of the forehead, temple, and cheek is drawn toward the medial angle of the orbit, and the eyelids are firmly closed. The skin is folded especially radiating from the lateral angle of the eyelids.
Wrinkles on the face
There are four muscles on the cheek: They are lying in the cheek from middle to lateral, from cheek bone to the upper lip: They form the nasolabial groove, from the side of the nose to the upper lip. This line is deepened in expressions of sadness. These muscles draw the angle of the mouth upward and backward in smiling. These muscles’s contraction creates tension on the cheek, deep nasolabial groove, and gummy smile.
Wrinkles around the mouth
There are a few groups of muscles around the mouth.
The orbicularis oris muscle is the muscle encircling the mouth and it lies between the skin and the mucous membranes of the lips. Contraction of this muscle closes and wrinkles the lips.
The risorius muscle draws the angle of the mouth outward when laughing.
A few muscles below the mouth draw the corner of the mouth down.
The depressor anguli oris is a muscle that originates from the mandible and inserts on angles of the mouth to depress the angle of the mouth.
The depressor labii inferioris muscle is a muscle of the face that draws the lower lip down and slightly laterally
The mentalis muscle elevates and protrudes the lower lip and wrinkles the skin of the chin.
The platysma muscle is a broad sheet of muscle originated from the the fascia covering the upper parts of the pectoralis major and deltoid going upwards to lower cheek and blend in with the muscle around the mouth. It draws the lower lip and corner of the mouth outward and downward.
Muscles lift up the upper lip. Muscles in the cheek involves in lifting upper lip. These muscles include the levator labii superioris alaeque nasi, the levator labii superioris muscle, the zygomaticus minor, the zygomaticus major. They all end in upper lip.
The tension and contraction of these muscles wrinkle the lips, chin, create lines around the mouth and chin.
