After a BBL if the Volume is Mostly at the Top and Sides, Will It Eventually Fall and Round Out?

    This is actually a pretty technical response, but the answer depends upon who did this procedure and how this procedure was performed.  If a great deal of fat was injected into the gluteal musculature, the musculature will be in spasm and will appear higher.  When the muscles relax the buttock will not appear high.  Just think about when you flex your buttocks - they appear higher.  If you need a revision after 3 to 6 months, find a plastic surgeon with ELITE credentials who performs hundreds of Brazilian buttlifts and Brazilian buttlift revisions each year.  Then look at the plastic surgeon's website before and after photo galleries to get a sense of who can deliver the results.  Kenneth Hughes, MD Los Angeles, CA

Brazilian Butt Lift (BBL) is such a misleading term; this procedure is neither "Brazilian" nor "lifting," it is fat grafting for buttock enlargement. Properly harvested fat (must be done correctly or else you're simply getting dead cells and "Mazola oil" injected--this won't survive and the results are only temporary until your body gets rid of the dead stuff) must be placed in tiny tunnels in order for the living cells to receive adequate oxygen and nutrients via osmosis until they heal and survive with their own blood vessels. Simply injecting big blobs of liposuction debris is easy, but won't last (see above).

And wherever it is injected, it stays. Some fluid swelling will go down (literally by gravity) as well as by absorption, but the actual cellular fat will (if all is done correctly and carefully) stay where it is; and if it survives, that's where it will be long term.

About 1/3 to 1/2 of grafted fat actually survives, so I would expect even poorly-positioned fat grafts to "go down" in volume by 1/2 to 2/3, but they won't "move." Sorry.

Massage will not help (except with swelling from fluid), but overdoing massage could damage whatever fat is still alive. Talk with your surgeon--another session, and better graft positioning, may be in order. Best wishes! Dr. Tholen

Hello dear!!
Thanks for the question and provided information as well. 
You are still early on the healing process, it can take up to six months to see your final results, so please be patient. After a BBL, only about 70% of the transferred fat cells will survive, so it is normal to see a minor reduction in your buttocks. If you have any concerns, I suggest you to follow up close with your plastic surgeon.
Good luck :)
