1, material selection: for autologous fat injection, because the survival time of fat cells after leaving the human body is limited, the fat used for lip augmentation is extracted after the surgeon arrives at plastic surgery, and more fat accumulates in the abdomen, buttocks, inner thighs and other parts.

2. Cleaning: air is an important source of bacterial infection, so the extracted fat must be stored in a needle tube, then taken to a vacuum environment to remove tissue fluid, and the fat is washed and disinfected with normal saline after being injected into the human body to reduce the infection rate.

3, anesthesia: the whole operation process of autologous fat lip augmentation can be completed with only one needle tube, and there is no need for incision and suture, so local anesthesia is generally used.

4. Injection: Insert the needle into the wet lip near the corner of the mouth and slowly push the autologous fat in.

5. Shaping: For liquid materials, it is difficult to evenly spread on the whole lip, so it is necessary to evenly push the materials away by massage, or let lip bead and other places hoard more according to the needs of surgical talents.

6. Maintenance: Autologous fat lip augmentation surgery is minimally invasive and does not require hospitalization. Usually, all kinds of normal activities can be carried out after surgery, but after all, free substances are implanted in the body, so doctors suggest taking antibiotics for a week to reduce the chance of infection.
