Many friends will find facial skin sagging, wrinkles, tear troughs, deepening nasolabial folds, sagging apple muscles, sagging upper lid skin, and increasingly visible eye bags after the age of 30, all of which are related to facial tissue volume loss. Facial autologous fat transplantation is an effective method to address facial aging caused by facial volume loss. Here is an introduction to what facial autologous fat grafting is, which is the application of swelling anesthesia to obtain fat from fat-rich donor areas such as the abdomen, thighs, and buttocks, and after precipitation or centrifugation, the obtained fat particles are then injected into areas with facial volume loss to restore a fuller appearance to the face. Numerous anatomical studies have confirmed the existence of different fat chambers in the face, which exist in different parts and at different levels and undergo different changes during facial aging. Therefore, when performing facial autologous fat transplantation, it is not a random filling, but a personalized transplantation for the characteristics of each fat chamber of each person. Advantages of autologous fat transplantation: 1. Targeted solution to the facial aging problem caused by facial volume loss. 2.After autologous fat transplantation, the recipient area is soft, there is no rejection reaction, and the surviving fat particles will be permanent fillers. 3.Multiple fat donor areas and plasticity can be performed on the donor area. 4.Effectively improve the characteristics of the injected area skin, increase the luster, improve pigmentation, and to a certain extent eliminate the effectiveness of acne (acne marks). The disadvantages of autologous fat transplantation: 1. After fat transplantation, a certain percentage of fat will be absorbed and liquefied. 2. In order to improve the survival rate of a single fat filling, it is not possible to over-inject, so two or more fat injections may be needed to achieve the final result.
