Sculptra. Am I going to have fat cheeks as a final result?? 1 day post op

Sculptra is a wonderful product that can restore lost volume to the face and fill in contour defects, including nasolabial folds. Sculptra is a watery solution that contains microparticles of poly-L-lactic acid (PLLA). When it is first injected into the skin, the solution and the PLLA fill in the defects and lost volume. The liquid causes some swelling — which is undoubtedly what you are seeing now. The water will be absorbed in the next few days, reducing the volume greatly.
At the next stage, some of the PLLA molecules will be resorbed by your body and you may think that you are going back to baseline (your look before treatment). This is not the case. As the PLLA molecules are resorbed, they are replaced by new, long, strong strands of collagen that firm up and support your skin, thus filling in the defects and lost volume again — this time more permanently (up to 2 years or more). The new collagen also allows increased production of elastin, which improves skin flexibility. Let this entire process play out before judging your results. Usually 2 or 3 treatments one month apart and results are gradual. If you only had one vial, I sincerely believe you will not look over-treated. If you are not thrilled with how you look in the next month or so, please contact the board-certified dermatologist who treated you. I suspect, though, that you will be very happy and will not have to make that call!

Thank you for sharing your question and photographs!  Most likely your current results are the result of the carrier fluid used to introduce Sculptra into your face.  This fluid is quickly absorbed by your body over the first 24-48 hours to largely restore your pre-treatment appearance.  Sculptra provides gradual improvement over the first 6-8 weeks in younger patients and up to 6 months in older ones.  Hope this helps.

Your swelling should go away quickly.  Sculptra takes a few months to work. This should only be a temporary side effect of the injections.  Your injecting physician should be able to comfort you with the same advice.
