Can I Get BBL After I Already Got Butt Implants?

Hello dear!
Thanks for the question and provided information as well.
Yes, this can be performed. Find a surgeon with enough experience with this procedure and that you feel conforable with.
In general, you need to be physically healthy and at a stable weight, have realistic expectations, be a non-smoker and your BMI needs to be 30 or less.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

Fat injections can be done into the buttocks even with subfascial implants. But the fat can only be placed right under the skin and its survival is also very unpredictable. There is also the risk that if some of the fat was inadvertently injected into the buttock capsule, an infection was likely result. Thus fat injections now is not going to be good option. Changing to a larger buttock implant size is your only choice, but with existing 565cc implants, the best size increase you are going to get is only about a 30% size increase. The reality is that you can get a better buttock size but it is never going to be what you ideally want...as it is now apparent that your ideal result is not surgically possible.
