Correction of changes in the lower third of the face is one of the most relevant topics in aesthetic medicine. This part of the face has its own characteristics, since the muscles located in this zone perform a huge load. Their direct functions, in addition to providing facial expressions, are chewing and speech. That is why it is much more difficult to correct changes in the lower third of the face than in other areas. It is necessary to take into account the specifics of the work of the muscles of the lower third of the face when injecting botulinum toxin. One of the most common reasons for visiting a cosmetologist for interventions on the lower third of the face is hypertonicity or spasm of the chin muscle.

Peculiarities of the structure and functioning of the mental muscle

The chin muscle is called musculus mentalis in Latin. It starts from the cellular protrusions of the incisors of the lower jaw, is partially covered by the muscle that lowers the lower lip, and is attached to the skin of the chin. The function of the mental muscle is to lift the skin of the chin and thus form the mental fossa. Hypertonicity or spasm of the mental muscle often occurs as a result of facial habits, for example, chewing on one side, grimacing, and so on. Such a state of the mental muscle distorts the appearance of the face and, of course, provokes the formation and aggravation of mimic wrinkles with age.

Why spasm of the chin muscles makes the face ugly

The peculiarity of facial changes with hypertonicity of the chin muscle is the close connection of all the muscles located in the chin area. A spasmodic chin muscle looks like an ugly protruding ball, while the muscle itself pulls along the fibers of the muscle that lowers the lower lip. Thus, the expression of the face is distorted, deep wrinkles are formed in the chin area, and the appearance of a person seems very unpleasant. Given the specifics of the structure and functioning of the structures of the lower third of the face, such a condition is quite difficult to correct.

What therapeutic measures will help relieve spasm of the chin muscle

There are several ways to eliminate the hypertonicity of the chin muscle. There are complexes of special exercises used as facial gymnastics. Such exercises can be quite effective, but more as a prevention of hypertonicity of the chin muscle. With a spasm of the chin muscle formed, gymnastics will not be effective enough. Techniques for massaging the muscles of the face, including the chin, bring a good effect, but rather short-term. The most effective method for correcting hypertonicity of the mental muscle is the use of botulinum toxin injections. Even persistent spasm can be removed by injecting 5 units of the drug directly into the muscle, 2.5 units in each abdomen. In this case, one should take into account the fact that the action of botulinum toxin & nbsp; in the muscles of the lower third of the face, it can end faster than in the muscles of other areas, which is associated with their greater activity.
