Are Butt Implants Safe After Having Brazilian Butt Lift?

Absolutely, having had fat transfer buttock augmentation (Brazilian Butt Lift) does not preclude you from have buttock implants now...RAS

Were the fat grafts successful?
The reason I say this is that implants in general seem to have a lot more problems than fat grafting. I have just spent the last half hour in this forum answering questions from patients who have had problems with their implants.
I do a ton of butt augmentation and rarely use implants, because of all the problems I hear about.
If you want additional volume a second procedure can be done and the results are more natural. I have done second procedures on two patients, both of them slender patients who preserved their original gains, but encouraged buy their results gained more weight just so I could graft the additional fat. They are both ecstatic and I'm sure would be happy to share their experience.
There is a reason why most of the guys that do a lot of butt augmentations use almost exclusively fat grafting. The results are better with less risk.
