What are the characteristics of autologous fat transfer? What are the indications? Autologous fat transplantation is to extract fat from certain areas of your own body where there is a lot of fat and transplant it to the areas with depressions or wrinkles. Since it is your own fat, there is no problem of rejection. The general survival rate of self-fat is between 30% and 50%, and more is needed for satisfactory results when injecting. Self fat transplantation also has the characteristics of shorter operation time, significant effect, painless procedure, less postoperative pain and quick recovery. Its indications are mainly for filling depressions or wrinkles. In the past, it could only fill depressions, but now, due to the improvement of technology, it can fill all kinds of wrinkles, including forehead lines, frown lines, crow’s feet, nasolabial folds and neck lines, etc. in a lasting and effective way without leaving injection marks on the face. When filling a larger amount, as an allogeneic material, there may be not only rejection but also flow, while there is no flow in self-fat grafting, which is completely integrated with the surrounding tissues. It also has the disadvantage that sometimes it does not completely solve the problem of laxity, and for more laxity in the face, it needs to be combined with a minimally invasive side lift.
