Fat can not only plump up temples and create lovely apple muscle, it can also be transplanted to other parts, such as injected into the lip red, so that some candidates with thin lips can have sexy and hot “peach lips”. Compared with other materials, fat lip augmentation is more realistic and natural, and the effect after lip augmentation is stable and long-lasting, so it is called “green lip augmentation”, which is easy to be accepted by the candidates. The survival rate of fat lip augmentation is about 50%, and the activated fat will grow together with the surrounding tissues and will not move, causing no damage to the original tissues. It usually takes 2 to 3 fillings to achieve the desired results. During this process, the candidate can also discuss with the doctor to create a red lip that suits the candidate’s own condition. Regarding the question of whether the transplanted fat will slide around, first of all, the transplanted fat is living tissue, and during the transplantation procedure and in the early days after the transplantation, the phenomenon of the transplanted fat deviating from the target recipient area will occur. This is because at this time the fat has not yet grown with its own tissue and may flow into the surrounding loose tissue, especially in scarred areas, recipient areas with poor tissue elasticity, and around ligamentous distribution areas. Therefore, when fat grafting is performed in these areas, the recipient area needs to be carefully examined, and subcutaneous scarring and fibrous strips need to be pretreated to reduce fat slippage and increase fat viability. Fat that has become viable after surgery will not migrate. Therefore, in the early stage of fat grafting, doctors will advise candidates not to rub or squeeze the injection site, not to do excessive exercise, and not to make exaggerated expressions and excessive chewing, in order to prevent the fat from migrating and affecting the efficacy of the treatment.
