After the depression is filled with fat, there will be a process of withering and absorption. Just like transplanting a leafy bonsai into another flowerpot, there is a certain probability that the leaves will wither. Transplanted fat is almost the same principle. The transplanted fat cells need to find a blood supply station quickly in their new residence, otherwise they will face the fate of apoptosis and absorption of fat cells.

If the filled fat cells don't find blood supply in the first time, fat cells can survive for about 3 or 4 days, while the transplanted fat cells need 3 or 4 days to reconnect to the blood supply system, and during this time, a large part of fat can't survive.

The filled autologous fat will be absorbed by itself, mostly within the first 3 months after transplantation. The main reason is that effective blood supply cannot be established in time after fat transplantation.

The survival rate of fat is the key to autologous fat filling.

Of course, the survival rate of fat can also be improved by adding PRP. If PRP is not added, you can also choose multiple injections to increase the survival rate. Secondly, after fat filling, the expectation of beauty seekers for its effect is too high, not as full as expected.

Due to the changes of people's physique and the metabolism of hormones in the body, there may be obvious contrast in appearance. If the beauty seeker is fat or thin after filling, it may affect the appearance. After all, once fat survives after fat filling, it will become a part of the body, just like the fat in its own body.
