Fat Transfer (long term, what to expect):Hello, I am currently considering facial fat transfer and have already meet with a handful of surgeons who are skilled and experienced. However, as I do more research on people's personal experience with fat grafts I'm noticing some develop lumps & bumps over time. What causes that? Also how does a fat graft age? I am very active (HITT workouts and weight training daily) and I am concerned about how a fat graft will age for my active body type. I appreciate any insight! Thank you!
