The first doctor operates. The "international practice" of facial fat filling is a few times. During the operation, doctors should estimate the survival rate of fat and strictly control the filling dose. If you fill too many fat cells at one time, it is easy to "hold the group" locally.

The size of the second fat particle. When filling, the fat should be refined as much as possible, so that the transplanted fat cells can fully contact with the surrounding tissues and establish a blood supply system. If the fat particles are too large and there is too much fat at a single point, it is not easy for the newly transplanted fat to establish blood supply to the surrounding tissues, resulting in a local cord-like mass.

What about autologous fat filling and sagging?

Autologous fat filling and sagging can be repaired. If the face droops due to force majeure (aging), resulting in fat accumulation, you can choose liposuction+lifting, and you can achieve a face-lifting effect after surgery.

If there is no sagging, swelling or induration in the initial filling position of fat, liposuction can be considered. If the filling time is long, and problems such as sagging, lump and induration have appeared in the operating area, then liposuction alone can not meet the repair needs.

Because liposuction can only be targeted at fat cells, there is nothing to do with skin sagging and induration. Not only that, liposuction surgery will aggravate the problem of postoperative skin sagging because it has no effect of tightening the skin.
