Breast augmentation with autologous fat transplantation will not cause changes in the endocrine environment of human body, will not cause harm to the breast itself, and will not have adverse effects on future fertility and breastfeeding. Autologous fat transplantation for breast augmentation uses its own tissue as breast enhancement material. Breast augmentation with autologous fat transplantation is a minimally invasive liposuction technique with few complications, which is different from the traditional method of removing large fat tissue or muscle. Because the traditional method may cause the defect of the donor site and leave obvious scars. The incision of liposuction is generally about 1-2mm, so the scar after healing is very small, located in hidden parts (such as navel, pubic hair, breech line, etc. However, autologous fat transplantation for breast augmentation is not perfect. Too much fat or too concentrated injection will lead to fat necrosis, dissolution and absorption due to insufficient blood supply, which is easy to cause infection, pain, cyst, fibrosis or calcification, breast deformation, fat necrosis and other sequelae. This requires the surgeon to have rich experience and superb technology. In other words, if you want to use autologous fat transplantation for breast augmentation for cosmetic surgery, you must choose a regular large-scale cosmetic surgery hospital. The effect of autologous fat breast augmentation is psychologically acceptable because there is no rejection reaction and the feeling of real breasts. The only drawback of autologous fat breast augmentation is that the survival rate of autologous fat transplantation is not very high, and some transplanted fat cells will be necrotic and liquefied. Therefore, autologous fat breast augmentation has a remarkable effect, which is the most ideal method and the method with the least complications.
