I'm confused. Is fat grafting permanent or not?
Doctor Answers 4
Fat transferred fat is permanent
Fat grafting results based on 35 year experience.
2. What you see at 3 months is what you get
3. In the wrong hands it produces irregularities and often requires touch ups especially in the face.
4. I have primarily used the abdomen where most people have "extra" fat
5. If you gain 20lbs. the transferred fat can increase in size!
Once this fat stabilizes, it is in fact permenant. However, in the facial region, aging will continue to occur and facial fat atrophy will continue.
One way to explain this is the following: in a hypothetical situation, if you had fat grafting done to only the right side of your face, but not to the left side, your right side will always have more volume than the left side, but will continue to age and have fat atrophy.
As far as thigh vs belly fat as the donor site, there has been no definitive study suggesting one is better than the other. What I generally ask my patients is the following: which body region do you have the toughest time losing fat from, and that is the region that I'll harvest fat from. In ladies its often inner knees and outer thighs, in males its generally around the belly.
Hope this helps clear things up a bit.
