Can Polylactic Acid injections give me a butt like this? I don't have enough fat. (Photo)

Sculptra can be used for slight improvements of contour of the buttock; however, it is not capable of creating the type of results from fat grafting or surgical implants.  The volume tends to improve slight contour irregularities, but in most patients is not a cost-effective treatment.

The anwer to your question is yes.  Kim Kardashian's Sculptra Butt Lift results are quite dramatic.  The cost will be significantly higher than a Brazilian Butt Lift (fat injections) because you will probably need more than 2 treatments to get those dramatic results.  The beauty of Sculptra is that you can see your results evolve gradually over time with no downtime.  If you are happy after 2 or 3 treamtents you can stop or keep going if you want more.  With fat, there is a significant downtime, swelling and you would have to wait at least 6 months before attempting to add to your results.  In summary, although the preferred route is fat injections, if you are not a candiate for surgery, and you are not concerned about the cost, then Sculptra maybe be the right option for you.  

I do this frequently in my practice and yes it can make the buttock grow but it takes a lot of vials.  You do not have your origional photos for us to know what you look like and how the response will be.  I suggest a formal consultation.  Best, Dr. Emer.
