Some patients ask: I have full face lipofilling, why is it uneven? The handling of the fat, the level and dosage of the filler will all affect the postoperative result. Why? 1, when the fat is extracted, it is unevenly sized particles, if it is directly used to fill, the small fat is absorbed after filling may be the formation of depression, while the large fat is absorbed after the formation of the bulge, that is, we see the unevenness of the transplantation after transplantation. This is why a series of special treatments are required before it can be used for facial fillers. For plastic surgeons, fat grafting is not only a physical job, but also a technical job. The concepts of “good at it” and “good at it” are two different concepts. The fat taken out by autologous fat full face filling is golden, which means that there is almost no breakage of capillaries under the skin when taking fat, and the recovery is fast and the swelling is not strong. 2, different parts of the particles of fat, divided into different levels, injected into the skin after the gap is very small, relatively speaking, will be filled with a more uniform and flat. It is just like: a pile of very fine and uniformly sized sand, laid on the floor, will be more than large stones or gravel mixed up to lay the floor to be flat. 3, from deep to shallow order, multi-dimensional three-dimensional balanced pavement filling, better control of the amount of fat filling. Similar to making a cake, you must first lay the bottom flat and lay a good foundation so that the top will not be pitted. How to deal with this situation when a candidate encounters it? Generally 3~6 months after the operation, the body itself can adjust itself, most of them can be restored to level, such as still uneven, need to go to the hospital for correction. Specifically according to the actual situation of the candidate, such as lipolysis, re-injection and so on. Some candidates ask: I am 49 years old, can I still do facial filler? Is the survival rate low? It can be done, the survival rate will be lower than young people. PRP can be added moderately to improve the fat survival rate.
