How long will swelling last around the mouth after injectable fillers?

It can take 1-2 weeks for swelling to resolve. I would wait a full 2 weeks before judging the results. If it is after the two week wait, you can have the filler reversed with hyaluronidase.
I hope this helps!

Hello. Thank you for your question. While everyone will have a slightly different experience, it is possible for some swelling and bruising to take up to two weeks to completely go away. For this reason, it’s best to schedule your appointment at least two weeks before a party or other big event to make sure you have enough time to heal before showing off your final results.
 

Bruising and swelling can last up to two weeks after injections.  Before your procedure you want to avoid aspirin, NSAIDS, and Vitamin E.  These can contribute to bruising.  Some patients find using the supplements Arnica and Bromelain helpful to minimize these side effects.

Swelling can last 1-2 weeks after injections. Keep in mind, a combination approach will give the most improvement. I recommend fillers for the folds themselves but also lifting around the mouth and cheeks to build underlying anatomical support. In our practice we combine sculptra with other fillers "layered" on top and lasers, rf treatments, J Plasma and peels to get the most conservative natural look. Please see a facial sculpting expert. Best, Dr. Emer

Thank you for sharing your excellent question.  Swelling after filler placement is quite common due to the thin nature of the lip tissues.  This swelling, and your results, will steadily improve over the first 3-5 days with up to 2 weeks needed for fillers to soften and the tissues to appear more natural.  You can reduce the swelling by using cold compresses and elevating your head at night with a couple of extra pillows behind your back.  You may want to also consider using Arnica Montana and bromelain as supplements.  Hang in there!
