How long does the swelling last after lip Juvederm? How long should I be icing?

Yes, swelling can be typical after lip fillers. Icing and cold compresses may give improvement as long as necessary. 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!

Thank you for your question! Swelling and bruising are common after lip injections and can persist up to two weeks.  Intermittently icing the area for the first few days and keeping your head elevated may help.  Also some patients find using Arnica and Bromelain supplements to be beneficial for healing. Best of luck!
