Answer : Fat transfer was quite popular many years ago. There are still some surgeons who use fat transfer and get very good results. Some surgeons question how long fat will last and how predictable the fat is. It is hard to harvest and place it again precisely. However, some surgeons get very good results and use this to great advantage. However, many surgeons find that injectables are the best approach for lip injectables. They can allow the lip to become symmetrical in a very controlled fashion. The injectable can be injected very precisely and exactly where it wants to be. There is no harvesting of tissue requiring a separate incision somewhere else on the body. The injectables also have varying degrees of longevity so you can choose your injectable depending on how long you want it to last and you can change the look of your lip depending on what you would like.
