Did you NOT tell the injecting doctor you were pregnant? I always require my patients to answer if they could be pregnant. Than I recommend to wait until after finished breastfeeding to have any fillers injected....
Thank you for your question. From the PI of Juvederm "The safety for use during pregnancy, in breastfeeding females, or in patients under 18 years has not been established.". While there is unlikely anything will happen there are no controlled studies showing that fillers are safe and thus it is best to err on the side of caution and not have filler until your child is born. I don't know who your friend is but you should seek the advice of a board certified Dermatologist when undergoing a medical procedure such as fillers/botox/etc. Regards, Dr. Matt Elias
