“Autologous fat breast augmentation/enlargement” as the name suggests, involves extracting excess fat from the body, such as the abdomen, thighs, and other areas, through liposuction surgery. After centrifugation and purification, the extracted fat is injected in a layered manner into the subcutaneous, fascial, muscular, and fatty layers of the breast.

In fat transfer to breast enlargement surgery, it is necessary to consider whether there is enough fat in the liposuction area and the tightness of the chest skin, which are among the conditions for surgical assessment. With sufficient fat and filling space, an average increase of 1-1.5 cup sizes can be achieved. If a larger increase is desired, it is recommended to undergo a second autologous fat breast augmentation (enlargement) surgery.

The most important thing about autologous fat grafting surgery is the “survival rate of fat cells”. The activity of the individual’s own fat cells varies, so the survival rate is also different. Generally, the fat survival rate is about 50-70%, and good postoperative care can improve the survival probability of fat. So, after the fat is transplanted to the chest, the importance of postoperative care should not be overlooked. After 3-6 months, the fat cells that survive in the supplemented areas will permanently survive.


Basically, the recovery period for autologous fat breast augmentation is not too long. There may be slight discomfort 2-3 days after surgery, but it won’t affect daily life or mobility. There may be some swelling in the chest due to fat filling and soreness at the fat harvesting site, but normal daily activities can be maintained. The three months after autologous fat breast augmentation surgery is a critical period for fat survival, requiring careful care. Never attempt to lose weight and fat, which could result in the loss of the hard-won fat in the chest. Instead, supplement with protein and other nutrients. Many women maintain and even upgrade their cup size after surgery.
