How long after BBL before transferred fat stays permanently?

Thanks for your quesiton.You are still in the early stages of healing.  The final results of a BBL are at 6 months where whatever fat remains is permanent.Dr. T

I will often allow patients to start sitting on the buttocks after 2-3 weeks.  I tell patients that by about 6 weeks or so what they see is what they get. In other words, the fat that will take would have taken already and a lot of swelling will go away in about that time as well.

You are still in early stages of healing. The swelling will subside in 6-8 weeks but the final results might be achieved in 3-6 months.  Follow your surgeon's post op instructions such as massaging your lipo areas and wearing a compression garment.

Thank you for your question.Fat survival after fat grafting depends on a few things such as technique used, anatomy, genetics, post operative care etc. Best case scenario, usually about 70% of the transferred fat will survive. Within the first 6 months, about 30% of the fat cells will not survive and will be reabsorbed and passed through your body. Whatever fat is remaining after 6 months, is what will remain as long as your weight remains stable. The best thing you can do to ensure fat survival is follow the aftercare instructions given by your plastic surgeon. Best of luck.Sincerely,

Too early to judge on the final result. You are still at the healing stage. The area in your lower back will be still bruised and swollen and this will take 8-12 weeks to settle. Wear your garment and keep your follow up with your surgeon.You have to give your body at least 12 weeks to start seeing results and final results can take 3-6 months depending the way your body heals.Best of luck!!
