The female breast is not only a functional organ, with the role of nurturing life, but also a physical organ, is the most significant symbol of female physical beauty. Full breasts are the symbol of female charm. Women’s pursuit of breast beauty is part of their nature. In medical terms, breast enlargement for stunted breasts is commonly known as augmentation mammaplasty, which has a variety of ways, the common ones being silicone gel implant augmentation mammaplasty and autologous fat augmentation mammaplasty. With recent medical advances, autologous fat breast augmentation has gradually become a hot spot in plastic surgery research. Autologous fat is derived from self-generated adipose tissue, which is extracted from the abdomen, thighs and other parts of the body, and then injected into the undeveloped breast after centrifugation and filtration, etc. There is no immune rejection of autologous adipose tissue, and as long as the transplanted fat cells survive, they will permanently exist in the breast, which is permanent in principle. Of course, as we age, the fat cells will gradually wither and die, and the breasts will gradually sag and sag, which is unavoidable. Autologous fat breast augmentation has the advantages of abundant source, easy to obtain, natural and beautiful effect, no rejection reaction and safe surgery, etc. Therefore, autologous fat is also called the soft gold of human body.
