What is masseter injection?

Masseter injection is a cosmetic method that uses Botox for local injection. Botox is a neurotoxin that can block signal transmission between nerves and muscles, causing temporary paralysis and atrophy of muscles. On the face, the masseter muscle is the main muscle that controls chewing movements and is located deep in the cheeks. When the masseter muscle is overdeveloped, it will lead to fullness of the cheeks and even the appearance of a square face or a "square face". By injecting Botox into the masseter muscle, it can relax. Gradually shrink, so as to achieve the effect of thin face and improve facial contours.

Advantages of masseter injection

1. effect is remarkable: The effect of masseter injection usually begins to appear 3-7 days after injection, and reaches its best state after 1-2 months. As the masseter muscle withdraws, the cheeks will gradually become flat and the facial outline will be softer.

2. 恢复期短：与传统面部吸脂或面部提升手术相比，咬肌注射属于非手术项目，几乎没有恢复期，注射后，患者可以立即恢复正常生活和工作。

3. high safety: Masseter injection is performed by professional doctors and has relatively low risks. Botox injection has been used in the face for many years. The technology is mature and there are few side effects.

4. reversibility: If you are not satisfied with the results, the patient can choose to stop using Botox. The masseter function will gradually recover and the effect will be reversible.

Indication for masseter injection

Masseter injection is mainly suitable for the following groups of people:

1. masseteric hypertrophy: The masseter muscle is naturally thick, which leads to plump cheeks and affects the appearance of the face.

2. Square face: I hope to improve my facial contour by thin-skinned face and make my face softer.

3. hypertrophy of temporal muscle: Hypertrophy of the temporal muscle can cause depression in the temples and affect facial symmetry.

4. facial asymmetry: The masseter muscle on one side is more developed than the other, resulting in facial asymmetry.

Operating procedures for masseter injection

1. Interview evaluation: Patients need to go to a regular medical and aesthetic institution for face-to-face diagnosis. The doctor will determine whether it is suitable for masseter injection based on factors such as facial condition and masseter development.

2. injection processBefore injection, the doctor will clean the injection site and may use a local anesthetic to reduce discomfort during injection. During injection, the doctor will inject botulinum toxin evenly into different parts of masseter muscle to ensure uniform effect.

3. postoperative care: After injection, patients should avoid pressing the injection site, do not chew hard objects, keep their head upright to prevent the spread of Botox, and usually avoid strenuous exercise and high temperature environments (such as sauna, steaming face) within 24 hours after surgery.

2. dose control: The dose of Botox needs to be adjusted according to the individual's facial conditions and needs. Excessive injection may cause stiff facial expressions.

3. postoperative diet: Within one week after injection, avoid eating spicy and irritating foods and keep your diet light to help recovery.

4. regular maintenance：咬肌注射的效果通常可持续3-6个月，之后需定期补打以维持效果。

2. 面部表情僵硬: Excessive injection may cause stiff facial expressions and affect naturalness. At this time, consider reducing the injection amount or administering a contralateral injection to balance the effect.
