This method can be used in the case of hypertrophy of masticatory muscles and even mandibular hypertrophy. The method of injecting hyaluronic acid injection into atrophic muscles in muscles takes about 10 minute, which is suitable for patients with less free time.

After1~ 2 weeks, it will change again, and the effect will reach the maximum in about 5-8 weeks.

However, hyaluronic acid injection has the characteristics of restoring its original appearance, which requires repeated injections.

However, most of the square chin refers to people with prominent mandibular angle, and only a part of the patients with square chin caused by hypertrophy of masticatory muscles are suitable for hyaluronic acid injection therapy, so the feasible objects are limited.

So after getting the correct diagnosis, we decide whether to treat it by surgery or simply by injection therapy.

If you really want to "fix" a patient with a prominent mandible that leads to a local chin, injection therapy has no effect at all. You should go to the hospital to see him.
