The most commonly used facial fillers are hyaluronic acid and autologous fat, and autologous fat is more readily accepted as a living cell of the human body. Regarding autologous fat filler, the most worrying thing for candidates is the survival problem, how much of my transplanted fat can actually survive? How much fat will survive? Which parts of the body are most likely to survive? Fat survival rates all vary from person to person. If the density and viscosity of the fat is just right, then the survival rate of the fat is high. If the fat is mixed with more grease and impurities, then the fat survival rate is poor. People who are thin, have less body fat and less pure fat have a relatively low fat survival rate. What factors affect the survival rate? 1. Extraction location: It is found that LPL activity is high in thighs and buttocks, followed by lower abdomen and upper abdomen. The easiest fat to survive is the inner thigh and inner knee, especially when doing fine grafting. If you need to do a large amount of transplantation there is no great difference. 2, the doctor’s technology: fat extraction and processing technology directly affects the survival of fat cells, professional doctors know better where to get quality fat. Well-equipped hospitals are able to use more advanced technology to ensure the integrity and activity of the cells have an extraordinary superiority. Which areas are most likely to survive? The areas where grafting is most likely to be successful are the cheeks, where the soft tissue is thicker and has a higher survival rate. In addition, absorption of fat grafts is actually a reduction in cell volume and not really absorption.
