Bump on the Inside of Lip from Juvederm

It can happen with Juvederm getting placed close to the lip mucosa (red skin). It can be removed by making a small stab incision and squeezing it out. You can also have Hyaluronidase injections and it will disappear in 2 days.
Please keep in mind this can happen in the best of hands and does not necessarily mean that your physician is not good at doing this.

Don't despair and don't distrust your doctor. If some product moved to an area that is felt inside on the mucosa, it can be removed by a small needle and pressure by your doctor or by placing hyaluronidase in the area, provided you are not allergic to this injection.

The bump can be a collection of Juvederm. It could be a small cyst (mucocoele) that was inadvertently injected or it could be a small liquefying hematoma. Most of these are benign occurences that are of little long term significance and should resolve. Juvederm can be treated with off label use of hyaluronidase but be prepared to accept a loss of the correction acheived.
