Liposuction for breast filling refers to autologous fat breast augmentation, which can be maintained for about five to ten years, but due to the difference in the number of injections, supply of own fat, and post-operative care of each person, it will affect the final maintenance time. 1. Number of injections: Generally speaking, autologous fat breast augmentation surgery requires several injections to achieve satisfactory results, usually about three injections. If the number of injections is low, most of the fat will be absorbed by the body and less fat will be hoarded in the breasts, and the time of maintenance will be reduced accordingly. 2. Own fat supply: autologous fat breast augmentation needs to extract fat from parts of the body with high fat content, and there are differences in the fat of each part. If the fat cells extracted from the thigh root with higher activity, the maintenance time will be longer. 3. Post-operative care: after the operation, you need to carry out appropriate care, if the chest is violently squeezed, traumatic collision, etc., it will lead to chest damage, affecting the maintenance time and effect of autologous fat breast augmentation. At the same time, the duration of breast augmentation also varies among individuals, and is closely related to the age and physical condition of individuals. To sum up, it is recommended that women should standardize the injection under the guidance of physicians and take care of themselves accordingly, and should go to the hospital in time if there are special circumstances.
