1. Filled fat is unevenly distributed. In order to distribute fat cells as evenly as possible, repair surgery is needed. The fat in the filling part is taken out and then redistributed. At this time, the experience of the restorer is very demanding. You must find a good doctor and try to avoid the second operation.
2. Due to the doctor's experience and injection technology, if there is too much fat or the injection is too concentrated, a lot of fat will pile up together. Due to insufficient blood supply, fat cells will be necrotic, dissolved and absorbed, which is more likely to induce infection.
3. The above problems are easy to solve, especially "fat embolism", which may cause blindness, shock, hemiplegia or death during the operation. Of course, this is the worst expectation. Finding a reliable dean can avoid these risks well, and I also have friends with good fat filling effect around me. I hope you can have a rational plastic surgery.
