Is Sculptra safe to fill in dimples on butt?

Sculptra can be used to fill in Buttock dimpling.  In this case ,because it is post BBL, no subcision is needed.  If the dimpling is due in part to cellulite, I will also subcise, my preferred method is with my Cellulaze laser, and then inject the Sculptra.

Smoothing out
dimples on the buttocks with Sculptra is an advanced procedure. To
get a beautiful and uniform result, the Sculptra must be properly
diluted and carefully placed. Otherwise, it could look lumpy and
uneven. Sculptra stimulates your body to produce the collagen that
will fill in dimples and if desired, create a rounder, fuller look to
your buttocks. The Sculptra microparticles dissolve as they are
replaced by the new collagen your body produces. Results can last up
to two years. Another option is to have a Cellfina treatment for
these dimples. This treatment actually cuts and releases the fibrous
bands that create the dimple. Once they are cut, the body fills in
the dimples with your own collagen with results proven to last at
least three years. Sometimes a combination of Cellfina and Sculptra
are necessary if the dimples are quite deep. Please find a
board-certified dermatologist who is expert at contouring and
smoothing the buttocks with Sculptra.  

Thank you for your question.  I do use Sculptra for patients who have some uneven fat loss from bbl procedures or dimples from steroid injections/previous trauma, or for patients who want to simply enhance their buttocks.  I would definitely visit with someone who has experience with Sculptra buttock injections.
