As we age, the facial skin will gradually age, the skin will gradually sag, the cheeks will sag and the upper cheeks will collapse, most of the reasons are due to the displacement and sagging of fat tissue. Autologous fat facial filler is a popular and popular surgical method that does not produce rejection and has long-lasting effects. The recovery time of facial fat filler varies slightly according to individual differences, and the specific process is as follows: 1. The fat filled into the face establishes contact with the surrounding tissues, especially blood circulation, because only with blood supply can the filled fat become viable. 2.Fat that has established complete blood circulation survives, while fat that has not established blood circulation perishes and is slowly metabolized and absorbed by the surrounding tissues. Within three months, the fat in the filled area can be gradually absorbed and stabilized. Generally, the surviving fat is more stable in three months after fat transplantation, and the fat filler can present permanent effect. Therefore, the overall recovery time of fat filler takes about 2-3 months. If secondary fat filling is needed, note that the interval between two procedures is usually about 3 months.
