Very swollen after Restylane injected into a deep vertical lip line above my upper lip. Is this normal?

It is not unusual to have a swollen lip after a filler injection. This is a result of the filler itself plus minor bleeding that can occur under the skin. You just need to wait it out. This typically lasts a couple of days. 

It is common to get swelling after fillers into the lips and lip lines. It is not normal to have irregularities or severe swelling. If you are unhappy you should speak to your physician and have the area injected with hyaluronidase, an enzyme that reverses the hyaluronic acid filler. For the next injections, consider Restylane Silk with cannula injection, this technique will limit the pain, swelling or bruising after the filler placement. It often takes up to two weeks for swelling to subside on its own. Find an expert in filler injections for your future treatments. Best, Dr. Emer.

It is absolutely normal to have some swelling in the lips after injecting the vertical lip lines with Restylane or other fillers.  It usually takes a few days for the swelling to completely resolve.  I would take the normal post-tx precautions like head elevation, icing, and even an anti-histamine like Benadryl to help with the swelling.  If it is worsening or if you are concerned, I would contact the doctor for their advice.  The nice thing to remember is that a HA product like Restylane is completely reversible with hyaluronidase, if you are unhappy with the results.
