Fat transfer might look great for up to 2 years. But it is expensive procedure, thus I'd like to get evidence based knowledge that does it really stay and start living in the spot where it was injected? Is it really a safe procedure. Why there is no true evidence base for this? I can see patient of TJM in San Francisco has few reviews up. First she has over stuffed look and 5 years after it looks like none of it stayed and its only the tight skin left from the aggressive facelift (sidepull).
