Face filling is to fill the face with suitable materials to make the facial skin fuller. Commonly used facial filling methods include autologous fat filling, collagen filling and hyaluronic acid filling, and the specific operations of these filling methods are also different.

Autologous fat fills the face. In this operation, a proper amount of fat is absorbed from the thigh root, waist and abdomen of the beauty seeker, and these fats are separated and purified to form compound fat particles, and then these fat particles are injected into the designated position of the face by injection to achieve the purpose of filling the face. This method has high safety, and there will be no allergy or rejection after operation. Usually after one or three times of filling, it can reach a relatively stable state.

Hyaluronic acid or collagen fills the face. Both of these methods are to inject proper amount of hyaluronic acid or collagen into the depressed part of the face, but the effect of these two operations can last for about six months to one year.
