Is Bellafil the same as PMMA? If so, why can't it be used for buttock augmentation if it is safe for the face?

I don't recommend Bellafill for the buttocks. Sculptra can be used to improve the butt. Keep in mind, these areas need numerous vials of Sculptra over time to build volume, and in some instances the results are subtle and will need to be combined with fat or implants to achieve desired results. It should be combined with RF treatments to get the sculptra to work even better/stimulate it to produce collagen such as venus legacy / exilis ultra / thermage / inmode forma or contoura. I recommend seeing a body shaping expert for a formal evaluation. Best, Dr. Emer.

The active compound in Bellafill is PMMA.  It could theoretically be used in the buttock, but that would be considered an off-label usage because it is not FDA approved to be used in that area.  The cost of Bellafill is also fairly high and the buttock is a fairly large area, so potentially the cost would be prohibitive for most people.  

Thank you for your question. Technically, Bellafill could be used in the buttocks but it is not economically feasible for most people. Each syringe of Bellafill contains 0.8 cc and will roughly produce the same amount of volume over time. It takes 5 cc to make one teaspoon, so that would be over 6 syringes of product or over $5000 per teaspoon of volume gained. Alternatively, Sculptra Aesthetic can be used with each vial producing about 5 cc of volume over time. This can also take a large number of vials but this at least gets into an area of affordability for some people.Lastly, Emsculpt is a new device that enlarges the buttocks muscles while giving a lift.None of the above options will give an equivalent result to a BBL (Fat Transfer) if you are looking for a sizeable volume increase.I hope this was helpful - Dr. Moore.
