With the Brazilian Butt Lift, what I typically see is that whatever volume you have by 3 months is permanent. You can see some photos on my website showing before and after pictures of the Brazilian Butt LIft. I will have my staff upload some pics from 3 months as well as of the same patients at one year. You will see that there is no visible change.
I have been performing this procedure for over 12 years now and have seen my patients at about 10 years after their surgery who have as much fullness 10 years after surgery as they had at 3 months.
