Hello: Autologous fat transplantation has advantages and disadvantages. For example, transplanted fat is the body's own fat particles. As its own tissue, its biological characteristics are far superior to other artificial materials, so it is harmless to the human body itself, and the probability of immune reaction and rejection is very small. The second advantage is that fat transplantation in your body will not cause changes in the endocrine environment of the human body, and the impact on the human body is much smaller than other body shaping and slimming. The disadvantage of this operation is that the survival rate of transplanted fat is relatively low (generally reported as 30%-70%), and sometimes it is necessary to adopt the method of "small amount and multiple times". In addition, due to the unstable treatment effect, this operation has not been widely used. I wish you the best of health!
