An interesting question raised by a prospective plastic surgery patient was that, can the liposuctioned fat from her daughter or sibling, be used in the place of silicone implants on her buttocks?. We have reported earlier about Brazilian Butt lifts, using liposuctioned fat to get fuller bottoms. Here if the fat is of another person, body rejects it, if its implanted into your body. If you use it, one would need to take anti-rejection drugs for life to sustain the fat.
