Injector Hit Nerve in Cheekbone W Juvaderm and Eye Twitching?

Normally there are no major nerves near the cheekbones that can be injured during a Juvederm injection.  The only major nerve and blood vessel in the region is under the eye.  Sounds like you may have had some bruising and swelling that may have caused the twitching and asymmetry.  This always goes away as the swelling resolves.  You can alternate warm and cold compress to accelerate the healing.  If the symptoms persist visit your doctor.  The color change is not due to hitting a nerve but possibly from injecting the filler too superficially.  If you are not pleased with the result, you can inject the antidote (hyaluronidase) and start over.

There is a sensory nerve (infraorbital nerve) that lies along the upper cheekbone that can be irritated by filler injection. That nerve, however, does not control muscle movement (i.e. twitching). Trauma to the nerve, however, can cause swelling and pain that takes a few weeks to resolve. As long as there is no allergy or intolerance, NSAIDs (such as ibuprofen, naproxen) can be helpful for nerve inflammation. It is certainly worthwhile to consult with your provider first, especially if the twitching lasts longer than the swelling.
