My Face is Still Swollen Four Weeks After Getting Juvederm, What's The Cause?

I am slightly concerned that you went back for what you called a "touch up". Juvederm touch ups are not recommended unless very specific steps are followed: 1. Did you pay for the touch up? If NOT, I am even more concerned. Was it a new syringe? 2. Syringes of filler are sterile when they are opened and need to be used all at once. Unless you really know this injector and his/her practices on keeping people's syringes (which can really only be done for a few weeks maximum), you could have gotten a touch up from a syringe which was not actually yours, or that was somehow contaminated. It is NOT normal to have swelling 4 weeks later, but more than that, I am very concerned about this touch up, and what possibly happened as a result of this.

Swelling 4 weeks after Juvederm is not normal. Juvederm does tend to attract and hold water and tissue fluids which may be causing the swelling. Perhaps too much product was injected. Although very unusual, soreness may indicate a reaction to the Juvederm. You need to be examined by your physician.
