From the photos it looks like the lips were injected improperly and there are bumps. If the bumps do not go away I would consult a board certified dermatologist to dissolve these bumps and have them re-injected properly.
Yes but it may take a few weeks. try warm compresses and massages. If still unhappy injection of hyalurondiase will dissolve the Restylane. But the cost would be $750 in most offices...
I suggest waiting a few days and if it does not go down with some icing and mild compression, I suggest reversing it with hyaluronidase. Id see a different injector for your next treatment. Best, Dr. Emer.
It is possible that you have some swelling so I would not rush into doing anything yet but I think that you are likely to have lumps that you will not be happy with. Give it a few days and then go back to your doctor and see what they say. I would not let anyone try to "fill in" or "even up" your lips. You should have this dissolved and star over if you have unevenness or lumps. If you are not comfortable with this doctor, see someone else but if you are comfortable with their training and feel that you just might have had an isolated bad result go and speak to them first
