Juvederm lip injection: after 3 months one side looks very swollen and asymmetrical, will the swelling go down? (Photo)

At this point all of the swelling has most likely resolved. What you are left with is inappropriate filler placement. I would have the filler dissolved with Hyaluronidase and start over. Make sure you find an experienced injector. Best wishes.

At three months all swelling is resolved.  If you have concerns about asymmetry I encourage you to return to your injector for an evaluation.  You can either add more product to attempt to even things out or have the product dissolved with hyaluronidase.

It isn't typical to have a flare up of swelling this long after lip injections. This can be reversed with hyaluronidase. I recommend getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer

Thank you for your question.  It is also advisable to avoid any NSAID’s before and after treatment as they tend to thin the blood and increase the risk of bruising and swelling.  It is common to have some swelling after fillers for lip augmentation which can take up to 2 weeks to resolve. You can apply cold compresses to the area to help reduce swelling and bruising.If you have any other concerns please contact your treating physician. Best of Luck!

Uneven filler that is present after 3 months is not due to swelling most likely.  To make the lips more even some either needs to be dissolved or more added to the opposite side. Please follow up with your treating physician to work towards making lips more symmetrical.
