The depth of injection is directly related to the effect. If the injection depth is too deep, the effect is not obvious. If the injection level is too shallow, skin protrusion, muscle stiffness and even redness will occur.

2. Injection dosage

3. Injection position

The location of injection is also closely related to the effect. Some people see "a little fake" at a glance after injection, which may be related to the injection position. If the injection positions on both sides are different, the unnatural will be more obvious.

4. Doctor's aesthetic standards

The level, dosage and location of injection are largely related to the doctor's skills and surgical experience. Therefore, when choosing a doctor, we should not only screen his qualifications, but also look at his personal aesthetic standards.

5, drug quality

You need to choose a safe and regular drug with the word "medicine" approved by the State Administration of Pharmaceutical Products. Before the injection, the doctor will show you the name, batch number and production date of the drug used. If you choose three no products produced by informal manufacturers, the consequences will be unimaginable.
