Causes of Extreme Swelling Post-Juvederm? I've had It Several Times With No Problem.

True allergic reactions with Juvaderm are rare, but can occur. Perhaps this is what is going on. You should your doctor immediately and be evaluated. You may require a short course of steroids to help decrease swelling and stop any allergic reaction.

Swelling at the injection site can happen but I have never heard of the entire face swelling.  It sounds as if you are having some reaction - perhaps to juvederm and perhaps to something unrelated.  You should return to your doctor and consult them right away.

Swelling after Juvederm is common, but it sounds as if yours is excessive and not what you've experienced in the past.  You may want to check with your injector to make sure he/she used the same amount of product.  If more was used, you may be over filled or have more swelling.  If you have excessive bruising, this can cause more swelling as well.  Juvederm can be dissolved by Hyaluronidase so that is another option if you are over filled.  Finally, if the area is red and tender, you may have an infection so definitely return to your injector to be evaluated.

If you had bruising, then you had a little bit of bleeding that could explain the significant swelling, blood in the tissue, this should resolve in 3-6 weeks. However you need to make sure this not infection, need immediate examination.Also ask you injector, what exactly was injected and where was it purchased from. Get the lot number and check with the company about the lot number. There are lots of fake fillers from china, india, etc

 I have used soft tissue fillers like Perlane and Radiesse many times for Cheek Augmentation, not the thinner fillers like Restylane or Juvederm that are meant to be placed within the layers, of the skin and not within the fatty tissues like the thicker Perlane and Radisse.

  Having said all that, IMHO, it sounds like you may have had an injection hematoma that caused the pronounced bruising and swelling.  You should go back to the MD that did the Juvederm injections for evaluation and possible treatment recommendations.

Juvederm is hyaluronic acid, a substance abundantly present in your skin. Juvederm is manufactured as a by- product of a bacterial (Streptococcus) culture. Some traces of STREP. protein may be present in Juvederm.
Moderate swelling after Juvederm injections can occasionally occur.
Severe swelling, like the o e you describe, isvery rare. You may have become allergic to the trace of protein in Juveder. Or to the Lidocaine in case you had one of the newer forms of Juvederm injected. A third possibility is an infection, but with this much swelling I would expect you to have pain and a fever. This would be an emergency for which you would need the services of an Infectious Diseases specialist. Finally, it could be severe bruising, easily recognizable by the purple color. If it is allergy, it will slowly
If it is an allergic reaction, it will gradually subside.
It is important to have Intradermal tests with Hyaluronic Acid and with Lidocaine.
