Extracting fat from your body is simple, without the cost of materials, which is equivalent to "waste utilization". It can be used not only for breast enhancement, but also for other parts of your face, which is very affordable. Generally choose fat-rich parts, such as abdomen, thighs or buttocks. After screening by centrifuge, the pure adipose tissue was transplanted to the site to be filled, and the perfect effect was achieved. Autologous fat generally has no sequelae, because it is its own tissue, which is non-toxic and harmless after transplantation and lasts for a long time, and there will be no sequelae and rejection. But I suggest you let a doctor with postal experience do it, which is safer.
