In fact, aging itself is a natural fat loss process, the top gradually becomes smaller and deeper, such as tear troughs, nasolabial folds, marionette lines, and the bottom increasingly produces sagging, such as doe-eyed flesh, blurred contour lines and other problems. This requires facial addition and subtraction, transplanting the excess fat to the location where it is needed. So many of the candidates for facelift are older, usually around 40 to 50 years old, does age have an effect on the survival rate of fat? In fact, there is not much relationship between the two. After fat aspiration, it still needs to be purified before transplantation, and age does not have any influence on the survival rate, it does not mean that the fat cells are aging with age, and there is inertia after transplantation, it still has a strong vitality, and there is not much difference between transplantation and young age, so age is not an obstacle.
