Autologous fat filler can improve the overall facial contour and smooth out wrinkles by filling in facial depressions and wrinkles, making people look less old and haggard. However, at the technical level, it requires a higher level of experience and skill than hyaluronic acid injection. The material of autologous fat filler is taken from oneself and can be maintained permanently after filling. However, the candidates often overlook three factors that affect the post-operative effect: the doctor’s skill and experience, the survival rate of the fat, and the absorption rate of the fat by themselves. Many candidates say that the fat is absorbed quickly after filling and the effect is not good, in fact, they do not really pay attention to the reasons that affect the effect. Autologous fat will be absorbed after being injected into the body, and its absorption rate is generally around 30%, and it may be absorbed up to 50% according to your own situation. 70% of people generally need to be filled 2-3 times to be stable. Autologous fat filler generally has a stabilization period of 3 months, during this period of time, pay attention to nutrition, do not lose weight, avoid strenuous exercise, do not massage, etc. If the effect is not satisfactory after a single fat filler, a small number of times can be taken, and after 3 months, supplementary injections can be made on the original basis.
