Autologous fat, hyaluronic acid, collagen, and Abeleve are all fillers, and these fillers can achieve better results when solving facial aging problems such as nasolabial folds, tear troughs, and periorbital hollows. However, compared with other materials, autologous fat has two obvious advantages: firstly, autologous fat is “own” and will not produce rejection, so it is supremely safe; secondly, the continuous effect of autologous fat filling is permanent. Therefore, the application of autologous fat in facial anti-aging is becoming more and more popular among beauty seekers. Fat from many parts of our body can be taken, the more common ones are fat from the abdomen, thighs and waist, if the candidates have conditions, fat from the face can also be used for filling, for example, fat from eye bags is often used to fill the tear trough. For example, fat from eye bags is often used to fill the nasolabial folds and temporal (temple) hollows. The two parts of eye bags and tear troughs are adjacent to each other, so it is easy to operate and more effective to fill them; fat from double chin or baby fat cheeks can be used to fill nasolabial folds and temporal (temple) hollows, etc. After fat transplantation, it can not only improve the unevenness and make the filling part and the whole face look more harmonious and natural, but also stimulate the collagen growth of facial skin, improve the texture of skin, make the pores shrink, discolorations become lighter and the skin moist and shiny. In addition to its application in anti-aging, fat can also be used for facial contour sculpture, for example, candidates with prominent cheekbones can fill the temporal area (temples) or cheek depressions below the cheekbones with autologous fat, making the sides smoothly transitional and the facial contour lines smooth, so that the cheekbones no longer look obviously prominent. In addition, autologous fat also plays an important role in the sculpting of forehead, nose and chin fullness and prominence. It is important to note that there is a problem of survival rate after autologous fat transplantation, some of it will be absorbed and some of it will survive, and it is difficult to control exactly how much fat will be absorbed at one time, so 2~3 injections may be needed. Nowadays, with the improvement of fat grafting technology, the increasing experience of clinicians and the increase of scientific and technological means, the survival rate of autologous fat grafting has been increasing. After fat transplantation, the previous survival rate is usually between 40% and 60%. Experienced doctors will optimize every detail of fat extraction, purification and replanting to protect the integrity of fat cells, and with the application of plasma extracts (mainly fibrin, growth factors, etc.), the survival rate after autologous fat transplantation can reach over 80%. The effect is permanently maintained after the survival of autologous fat transplantation. Compared with other parts of the body, the survival rate of fat after facial filler is usually higher because the amount of fat filled is generally less and because the blood circulation in the face is richer, while in other parts such as the chest, the fat filling may reach hundreds of milliliters at a time and the filling volume is larger, so the survival rate will be lower. The first problem of autologous fat filler is the difficulty of controlling the survival rate, in other words, it is not as accurate as hyaluronic acid, Avef and other fillers; the second problem is that nodules and calcification may appear after autologous fat filler. Therefore, when doing facial fat transplantation, experienced physicians will choose the most suitable level and try to expand the contact surface of transplanted fat, and it is multi-layered multi-point three-dimensional cross-filling fat, which is conducive to uniform transplantation and improve the survival rate of fat; usually the first time to complete 90% of the total transplantation, and then after 3-6 months to do the second transplantation to fill 10% and do the finishing cosmetic. Through two fat transplants, a satisfactory effect can be achieved. After autologous fat injection, because there are some traumas and needle eyes in local tissues, makeup cannot be applied immediately. We suggest that candidates should put on makeup at least 48 hours later, with light makeup, and normal makeup can be applied after one week. Be careful not to squeeze the local area within one week after injection to prevent changes in the shape of the filling site. If the injection is made in the nasolabial folds and temples, pay attention to the local expression movement not to be too strenuous after the operation, such as not to laugh and open the mouth drastically, etc. Autologous fat is soft gold, she will set off a huge wave of beauty in the new century, bringing the gospel to beauty lovers!
