How many pound of fat are needed for 1000cc of injectable fat?

Question

I understand that aspirate includes blood and other non-fat molecules that get washed away before it can be injected into the butt. To inject 1000 CC of fat in a BBL, how many pounds of fat would that be on my body? Also, how many CCs of liposuctioned aspirate would that be?

​Thank you for your question. It is hard to provided with a valid medical opinion without photos.  I would suggest to be treated by board certificated plastic surgeon with experience in this procedure, to get the best desired results.

Kind Regards,

In plastic surgery, when dealing with fat and other type of grafts, we routinely use volume measurements which is ml or cc. In order to get answer to your question, you should do some mathematics and, based on specific weight of fat tissue, calculate how much pounds or grams weights 1000 ml of fat. Plastic surgeons are not always good mathematicians but Google may be? Good luck.

Dear Luxxor,
It is not the weight in pounds that makes the difference in quality and quantity of fat, but rather the amount of fat and the distribution.  When you perform liposuction, around 75% or more of the aspirate is fat, the remainder being tumescent fluid, some blood and oil (ruptured fat cells).  If you want 500cc;'s of fat transferred to each buttocks, then you should have at least 1400-1500cc's of total aspirate (amount taken out).
Best wishes.
Dr. Taranow

There are really too many variables to accurately answer your question.

Fat has a specific gravity of 0.93.

1000ml X 0.93Gm/ml=930 grams/ 454g/lbs= 2.05 lbs.

Percentage of water and blood in liposuction aspirate can vary anywhere from 10% to 70%.

Plastic surgeons typically or at least should refer to a fat removed as actual fat and clearly differentiate Liposuction as spread as aspirate and fat as fat.  The separation process changes over time as the fat particles settle.

For this reason an accurate answer to your question isn’t possible.

I suggest focusing on variables you have control over primarily choosing the most talented and experienced surgeon for the procedure rather than technical aspects.

If you’ve not done so yet I suggest scheduling multiple in person consultations with experienced local board-certified plastic surgeons.

Simply using numbers alone is not a good way to predict procedure outcomes because of the variables involved.

Best,
