The reason of fat overload has a lot to do with the doctor who operated on you. Generally, the operator is not skilled enough to cause this situation. After forehead fat filling, you need to wait for more than one year before you can consider taking out forehead fat under the endoscope. And because the filled fat is usually messy, it is not suitable to take it out by suction, otherwise the forehead will be uneven. After the forehead is filled with too much fat, only minimally invasive forehead rhytidectomy under endoscope can remove the filled fat at the same time, and then flatten the forehead after operation. And don't try liposuction after fat filling, otherwise, because there are too many traumatic scars, it will take more than 3 years to perform endoscopic surgery, which will seriously lead to uneven forehead after repair and even lose the opportunity of endoscopic surgery.
