Autologous fat breast augmentation has been clinically proven over a long period of time and the technique is now considered to be more degree and safer. Compared with other fillers, fat cells have obvious advantages. Autologous fat cells come from the autologous body and are taken in abundance, which is safer, harmless and does not cause rejection reactions. The operation of autologous fat breast augmentation is meticulous and will not damage the breast ducts and other tissues, and it does not affect breastfeeding because the fat is not injected into the breast. Moreover, after autologous fat filling, the local feel is better and the shape is more natural. Although there are many advantages of autologous fat breast augmentation, the inability of its fat to survive completely is a concern for many candidates. Since the fat used for autologous fat breast augmentation mainly comes from the abdomen, buttocks, waist and other locations where the fat is more abundant and is processed and then injected, if the aseptic requirements are not met during the extraction, processing and injection process, infection may occur. In addition, if the fat extraction and fat injection are not done properly, hard lumps, nodules, cysts, calcification, etc. may also occur. Therefore, it is recommended that candidates go to regular hospitals and aesthetic institutions and seek experienced doctors. This can be done under hygienic and technically proficient conditions, which can greatly reduce the probability of risk.
