Facial fat filler surgery is usually performed by removing part of the fat from areas with high fat accumulation, such as inner thighs or abdomen, and then separating and extracting the extracted fat, after which it is injected into the desired areas of the face. The recovery process is as follows including the following points: 1. The fat filled into the face establishes contact with the surrounding tissues, especially blood circulation, because only with the supply of blood can the filled fat become viable; 2. The fat that establishes completed blood circulation survives, and vice versa perishes and is gradually metabolized and absorbed by the surrounding tissues; 3. The newly viable fat gradually grows and stabilizes, so that the face can achieve a good filling effect. Combined with the above, the recovery of facial fat filler takes about 3 months. In clinical practice, factors such as the size of the incision, post-operative swelling or fat absorption are related to the filling site and can have an impact on the recovery time after facial fat filler. If you simply fill the forehead or nasolabial folds, the initial recovery generally takes about 2 weeks; if you perform full-face filler, the filling volume is more and the operation site is more, and at the same time, the fat absorption also takes some time, and the initial recovery takes about 2-4 weeks.
