At which level does hyaluronic acid hit the chin

Hyaluronic acid injection into the chin usually requires injecting the product into the deep dermis or upper periosteum layer, and the specific layer needs to be adjusted according to individual facial structure and shaping needs. The filling layers of hyaluronic acid mainly include subcutaneous fat layer, upper layer of periosteum, muscle gap, etc. Different layers can affect the shaping effect and maintenance time.

1. Subcutaneous fat layer

Injecting hyaluronic acid into the subcutaneous fat layer is suitable for beauty seekers who need slight modifications to their chin shape. This level of operation is relatively simple, with a short recovery period, but weak shaping support, suitable for people whose chin basic conditions are still acceptable and only need minor adjustments. Short term swelling may occur after injection, and it is necessary to avoid applying excessive pressure to prevent displacement.

2. Upper layer of periosteum

Injection on the periosteum can provide stronger contour support, suitable for those with chin retraction or severe shortening. This level is close to bones, with a more three-dimensional and long-lasting shaping effect, but it requires higher anatomical skills from doctors. Attention should be paid to avoiding damage to nerves and blood vessels. After surgery, there may be a prolonged feeling of stiffness, which needs to be relieved with ice compress.

3. Muscle Gap

Injection into the gap between the chin muscle and the mandible can balance dynamic expression and static shaping. This level can reduce the compression of muscle activity on fillers and prolong maintenance time, but excessive filling may lead to unnatural expressions. After injection, frequent exaggerated facial expressions should be avoided.

4. Combination injection

professional doctors often use multi-level composite injection technology to lay the foundation contour on the periosteum, and then finely adjust it in the shallow layer. This method can balance shaping strength and naturalness, but it requires strict control of the dosage at each level to avoid a stepped appearance or excessive filling.

5. Special treatment

For those with thin chin skin, it is necessary to reduce the amount of shallow injection to prevent translucency. Patients with chin implants or severe scar constitution should carefully choose the level and, if necessary, cooperate with ultrasound guidance to ensure accurate positioning. Avoid high temperature environment within 48 hours after surgery to prevent rapid metabolism of hyaluronic acid. After hyaluronic acid injection, the injection site should be kept clean and dry, avoiding vigorous exercise or prolonged bowing movements. Reduce the intake of spicy and stimulating foods in diet, and supplement vitamin C appropriately to promote tissue repair. If there is persistent redness, abnormal hardening, or changes in skin color, it is necessary to contact a doctor for timely treatment. Regular follow-up visits can help evaluate metabolic status and, if necessary, administer supplementary injections to maintain effectiveness.
