The maintenance time of fat filler facial varies from person to person, some patients can maintain permanent after the fat is stabilized for 3 months after filling, while some patients need to fill 2-3 times to maintain permanent. Usually, 3 months after the role of facial fat filler, the non-viable fat is basically absorbed and the swelling basically subsides, which is the final effect after stabilization at this time, and theoretically the effect can be maintained for a long time. However, the aging of human body is slow and continuous, the skin can gradually sag and the effect of fat filler is gradually lost. At the same time, patients with facial fat filler need to pay attention to post-operative care. Proper care can increase the success rate of the surgery, such as avoiding such actions as chewing and sneezing drastically, avoiding direct pressure on the autologous fat-filled parts, and keeping the local area clean. In addition, appropriate cold compresses for the first 3 days after surgery and hot compresses after 3 days can accelerate the disappearance of edema.
