It takea 2 weeks for Juvederm to settle down and loo its best. Be patient and follow your PHYSICIANS directions. My Best, Dr C
I would say to wait at least a total of 7-10 days to see a true result. If you still have the puffiness, go back to the injector and have them take a look.
If the filler was not placed along the corners of the mouth, then more than likely this is swelling. Best to give it a few days to settle down.
It is not uncommon to have some swelling develop after Juvederm injections. Swelling to tends to travel downward as it dissipates, so since you had the nasolabial folds treated, the swelling is settling at the corners of your mouth. I would expect this to resolve within a week or so, but if you feel it is still present after a couple of weeks you should contact your injector.
