How permanent is a Brazilian Butt lift?

Thank you for your question. This is a very important question and one which will generate several different answers and opinions. The bottom line is that the fat that gets blood supply and nutrients from the surrounding tissue and survives will eventually become permanent but this process takes several months. The debate is on how much of the injected fat survives and in my opinion, that is dependent on technique (among other factors). Some surgeons claim very large volumes of injected fat (1000-2000 cc per buttock) but this is usually fat that undergoes very little purification and processing and often includes volume attributed to fluid, oils, dead fat cells, etc. I think it is more important to purify the fat and only transfer high quality cells with a high chance of survival. Quality not quantity. If you look at post-op photos of several PS's BBLs, they often take them very early post-op, or even on the OR table, so that things looks amazing and impressive....the problem is that very few of these patients are that happy 6-12 months after surgery because there is such a large change in fat graft volume that has long term survival. Hope this helps!

About 60% of the transferred fat will survive long term and be permanent; watch this video for more detailed information.Best wishes,Dr.Bruno

After several months the fat cells that remain will be permanent. They will increase and decrease in size with weight gain or loss. They should not get smaller with exercise if your weight stays the same. Your 100% correct that your buttocks soften after the procedure and have a natural and bouncy appearance. Make sure you find an experienced board-certified plastic surgeon to perform your procedure.

Thank you for your question. Fat transfer to the buttocks is permanent. This does not mean that you will not have changes with weight gain or loss; the fat cells can get larger or shrink. The results depend on the technique of the surgeon, experience, artistic skill and sculpting of the surrounding areas. With stable weight, you should maintain your new shape long term.

Dear marie_7890,BBL is considered as a permanent solution for buttocks augmentation. In most cases 30-40% of transferred fat will be lost few months after the surgery. Fat viability depends a lot of surgeon technique. The fat has to be placed back into the buttocks as soon as possible so that it has a greater chance of survival. It has to be placed carefully so that not too much fat is placed in only one area.Daniel Barrett, MD, MHA, MS

BBL is considered a "permanent" operation. In the first year about 70% of the fat stays and it does become natural and bouncy. Different techniques have created variability of results, but the best techniques will give such results. 

The controversy surrounding the "permanence" or "temporary" nature of the results buttock augmentation via autologous fat grafting speaks to the variable nature of fat grafting as a technique.
Technically speaking the results of fat grafting should be permanent in the sense that grafted fat which has become vascularized should not disappear several months post op.
However, there is an initial period, immediately post op where some of the grafted fat is lost. It is during this period that some may sense that their aesthetic outcome is fleeting. Every patient reaches a point after which the grafted fat which has become vascularized is permanent and the fat graft which has not will have undergone resorption. This is typically reached by 3-4 months post op. 
For some patients, the graft take vs loss ratio will be favorable and for others less so. There is no question that there is both variability in techniques as well as outcome. Patients can expect anywhere from 30-50% loss of volume.
As always, you should seek a board certified plastic surgeon (ABPS) who is experience in both the science and art of autologous fat grafting to help you understand the procedure and provide a reasonable idea of what to expect both immediately post op and long term.

Thank you for your question. With Brazilian butt lift we transfer fat from one area of the body to the other.  These fat cells are transferred in microinjections throughout multiple planes in the buttock tissue so that they can gain new blood supply and live in their new home, providing increased volume and shape to the buttocks. After surgery there is a predictable swelling process that mostly resolves over two months, when the final result really settles in. Around 70% of fat that is grafted is typically expected to survive long term. We also put a little extra to account for loss of fat post operative, which is reabsorbed gradually by the body.

About 50 to 70% of the fat survives long term. I have seen patients after a year or two and the pictures reveal that the gain is permanent. Perhaps this is due to injection technique, harvest technique, amount transferred.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA

Thank you for your question. With any fat transfer procedure, there is a possibility that a small amount of the fat cells may die after being transferred. This is patient dependent. Initially after surgery, there is some swelling which may appear firm. This is generally normal and a result from the trauma of surgery. It most cases, it softens over time. As we age, the skin naturally becomes more lax. There is no way to prevent that, but there are things that can be done to take better care of the skin and help to age gracefully. With regards to exercising, when we exercise, our body uses up our fat stores for energy. There is no way to predict which areas of the body fat will be harvested from when exercising.
