The time for lipofilling is relative, first of all it is longer than the general surgery. This is because it combines liposuction and fat grafting filler surgery into one. Also, after liposuction, it needs to be processed, depending on the case, into granular fat, nano-fat or fat gel, and this process also takes time. In fact, the real filler takes different time depending on the scope, but most of the time is spent on the preparation of materials. If you do a full facial fat filler, it takes about three to four hours, and the main time is wasted on liposuction and fat processing, so the real surgery time is not long. Does fat gel filler take longer? That is for sure. Fat gel is prepared after further refinement and centrifugation of the granular fat, and it is less efficient, so it must have some extended time. As for how long the extension is, it is mastered according to your dosage, so the time is different.
