Generally we are concerned about the survival rate of the fat, but in rare cases, the transplanted fat may also grow more and more. The fat undergoes metabolism after it becomes viable and may also increase with weight gain. This growth of fat beyond expectations may disrupt the proportions of the face or make the face appear less clear. This is a physiological increase and usually does not need to be addressed. Sometimes, however, the transplanted fat may be stimulated by various factors (the exact cause is unknown) to grow abnormally and form lipoma-like growths. If the lipoma-like growth grows larger and larger, it can be removed by inserting a liposuction tube into the tumor or by surgical removal. In addition, the addition of growth factors during fat grafting may promote the development of lipomas. Therefore, it is important to avoid adding any growth factors during fat grafting. Fat grafting is usually done in excess, but if more fat is grafted than expected, it may result in a localized fat overload, which may manifest as a bloated filler area. When there is an excess of filled fat, the metabolism of the fat can be accelerated by heat and infrared therapy in the early stage. However, the fat is still in the absorption period and there is swelling on the face in the early stage after the surgery, and it is not easy to determine whether there is really an excess. Therefore, it is recommended not to deal with it in a hurry, and you can wait until 3 months after stabilization. If the amount of fat survival is really too much, the excess fat can be removed by methods such as lipolysis or liposuction.
