I had sculptura and found out I was 3 weeks pregnant a week after. Will this harm the baby?

The evidence so far is that Sculptra should not have any effect on pregnancy.  Sculptra is based off of a natural substance and stays localized after injection.  The consensus recommendation is to not have injections during pregnancy or during breast feeding.

Some types of medicines have not been properly evaluated for safety during pregnancy. It would be unfair for anyone to comment on this as there are no studies that document the safety either way. Best, Dr. Karamanoukian Los Angeles

Even tough, we don't recommend to get injections during your pregnancy, but  you should not be too worries. The product injected in the face does not migrate to other part of the body let alone to the embryo. The product has to become blood born (get into your blood stream) for it to get to the baby. And many injectors are very careful not to inject near or in the artery or vein.  

The short answer is likely no.  Although cosmetic procedures are never studied in women who are pregnant or planning to become due to FDA regulations, the fact is many have been in a similar situation as you, and there is rarely any effect that can be linked to the cosmetic procedure were a complication to occur.  I'm sure everything will be fine, congratulations!!Best, Dr. Emer.

While there have not been studies examining the use of Sculptra in pregnant women, there should be no harm to your baby by having the Sculptra treatment done when you were 2 weeks pregnant.  The Sculptra does not circulate throughout your body but just stays in the area where it was injected.  You should hold off on further treatments until after your pregnancy and after breast feeding has stopped.
