Autologous fat can be injected into the chest not once, but many times. At present, most plastic surgery hospitals are injected three times. Because after autologous fat enters the chest, part of it will be absorbed by the human body, and the other part will stay in the chest and will not disappear. This is the long-term effect that autologous fat breast enhancement surgery can maintain. In other words, if the number of injections is less than three times and the amount of autologous fat accumulation in the chest is not enough, the breast enhancement effect will be greatly reduced and the surgical effect will not last long. Of course, the effect of autologous fat breast enhancement surgery is influenced by the level of breast enhancement doctors, because autologous fat breast enhancement has little risk, no adverse reactions and quick results. As long as the doctor's operating norms are correct, there will be no problem. Therefore, choosing a regular plastic surgery hospital and having a professional breast enhancement doctor can ensure the long-term effect of autologous fat breast enhancement surgery.
