3 days post Juvederm injection. The injector hit a blood vessel. Is this bruising normal or should I go back? (Photos)

Yes, bruising and/or swelling can be typical after lip fillers. It can take 1-2 weeks for final results. 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 and thank you for your question and photo.  Unfortunately, there is always a possibility of bruising and swelling with lip augmentation.  The lips are highly vascular and inadvertent injury to a small vessel can occur.  I would certainly recommend you continue the arnica topical and possibly by mouth, the ice should help as well. It usually takes two weeks for minimal swelling to resolve.  If you are concerned at all, I would reach out to your injector.  They will be happy to see you and ease your concerns. I hope this information helps and best of luck to you! 

This looks like a really big bruise. Arnica and ice may help, but it may take up to 2 weeks to fully resolve along with the swelling. If it gets worse instead of better then I would make sure to follow up with your injector sooner. Best wishes.
