Is It True That After a Yr the BBL Results Start to Fade?

I have heard from patients that they are told by some Beverly Hills Plastic Surgeons that about 10-30% of the buttock volume goes away with time after fat injection. In my personal experience with many Brazilian Buttock Augmentations in Beverly Hills, I find this not to be true. I have found that if the fat is harvested and processed gentely the fat cells are preserved and they do stay. One of the issues that I see in general is that some doctors don't add enough fat to the buttocks, so that when the swelling subsides then the buttocks looks small. This is not due to loss of fat cells but, lack of grafting of adequate fat volume!

About 60% of fat from the transfer is retained and the results are permanent. The size will change with your weight just as the rest of your body does. In other words, the fat acts like it was naturally there. You can get a good idea of the final result after 6 months.

A Brazilian Butt Lift involves fat injections into the buttock, giving a rounder, fuller, lifted buttock. When done using meticulous technique and respect for the fragile fat, the results are long lasting. The fat cells that survive the first 3 months after transfer, can essentially remain forever and has been confirmed with long term followup by MRI.  You need to make sur that you select a doctor experienced with this technique because failing to use special techniques to preserve the fat cells can result in a 50% death of fat cells which is too high. This has become one of my most requested procedures over the past year, with several cases being done per week. 

Hello dear!!
Thanks for the question and provided information as well. 
After a BBL, only about 70% of the transferred fat cells will survive, so it is normal to see a minor reduction in your buttocks, but then results should be permanent, as long as you maintain a stable, healthy weight. If you have any concerns, I suggest you to follow up close with your plastic surgeon.
Good luck :)

Fat grafting to the buttock region can be very successful if done judiciously and with gentleness in order to allow the transplanted fat to survive. Though it is hard to quantify exactly how much of the transplanted fat survives, it has been my experience that early volume loss (in the first 4-6 ) weeks, represents the time frame that I expect most of the volume changes to occur. Beyond that, small, subtle changes can occur, but are not as noticeable. I believe that over the next several years, continued improvement in the method of harvesting and transplantation will occur allowing for greater success in graft survival.
