Normally, filling with autologous fat does not cause sagging. Why? First of all, fat is not mobile and there is no need to worry about sagging due to mobility. Why? Let’s take autologous fat filling for the face. When autologous fat is added to the face, the “new fat” will be fixed in the filled area due to the blockage of the facial skin fibers. At the same time, in order to survive, the “new fat” needs to establish blood flow, and blood vessels will slowly grow to surround the fat to provide blood supply. Let’s say: fat is like a newly transplanted sapling, and fiber is like a fixed sapling stent, the establishment of blood vessels is like a sapling rooting process, with a stent fixed and then rooted to the soil, the fat will be very solid to stay in the filler site. Secondly, the doctors in regular hospitals are skilled, there will be no postoperative fat displacement. As we all know, the transplanted fat and the body’s inherent fat, are subject to the body’s “strict control”, not “want to go wherever”. As long as the doctor can fill the subcutaneous tissue with autologous fat according to the specific level and location of the facial depression, there will be no sagging phenomenon. Some people ask: I filled fat in the forehead, apple muscle and other parts, a few days after the upper eyelid, cheeks “swollen”, how is this? The essence of this phenomenon is not that the transplanted fat has moved downward, but that the inflammatory edema fluid in the transplanted area flows downward. Finally, the sagging of the face has nothing to do with the amount of fat filled. Why? Because the subcutaneous tissue consists mainly of fat cells, fibrous intervals and blood vessels, and the fat cells are in the form of fat lobules within the fibrous intervals, and each fat cell is surrounded by capillaries. The transplanted fat is taken from the candidate’s own body, and when it becomes viable, the fat will have the same properties as your own facial fat; your own fat is fixed and will not cause facial sagging. Why do some candidates experience sagging after lipofilling? There are two possible reasons: 1. The location and level of the fat filled by the doctor is not correct. Solution: Go to the whole hospital to find a skillful doctor for fat filling. 2, the face is loose and sagging seriously before filling. Solution: It is recommended to do face lifting first.
