BBL: injecting under muscle for maximum fat survival?

Hi... thank you for the question... the amount of fat will depend on the fat tissue that could be harvested... Every PS have different criteria, About the technique for the Fat infection.. In my practice with caution i use under the muscle and over, by multiple passes... this technique have give me great results over the time. 

You are correct, fat tends to survive better within muscle because of its rich blood supply. Most BBL surgeries involve some fat injection within the muscle. However, this is also where larger blood vessels are present and fat injected into these vessels can lead to embolism and death. There are several reports of death during these operations because of fat injected into the gluteal vein. Regarding volume injected not everyone measures the fat the same way because if the fat isn't strained and has a larger content of the lidocaine tumescent solution they may count that as well when they claim 2500cc of fat. Realistically this is probably similar volume to someone saying they injected 800cc of fat. You really can't compare straight volume of fat between surgeons because of this. Look at their gallery and reviews for a better idea of possible outcomes. Search for a surgeon certified by the American Board of Plastic Surgery to minimize potential major complications. Best of luck

Hello dear!
Thanks for the question and provided information as well.
Injecting fat under the muscle is dangerous and carries many health risks. This is why no doctor should incur in this practice.
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 :)
