What type of molecule is used for hyaluronic acid fillers to treat nasolabial folds?

For filling nasolabial folds, hyaluronic acid with large molecules is recommended as it provides better results. Large-molecule hyaluronic acid offers stronger support and can significantly improve the appearance of nasolabial folds. The specific procedure for filling nasolabial folds is as follows:

1. Preoperative planning: The doctor evaluates the patient's condition and performs preoperative design according to individual needs.

2. Local anesthesia: Apply local anesthesia using 0.2% lidocaine to the nasolabial fold area and surrounding regions.

3. Injection: Select an appropriate type of hyaluronic acid and perform deep injections, placing the hyaluronic acid on the surface of the basal bone of the nose. Additionally, inject small amounts into the subcutaneous tissue of the nasolabial groove area, using a technique of multiple small injections with moderate adjustments. As the procedure involves risks, it is recommended to undergo treatment at a professional medical facility.
