“Side Effects of Juvederm Two Months Later - Thousand Oaks, CA”

Injections were painful even with numbing, but tolerable. Bad brusing on one side that took over a week to go away, but after that it looked great. I did it because I have marionette lines which aged my face. Two months down the road, however, I suddenly have a visibly swollen lump at the injection sites on the same side of my face that initially bruised. This happened overnight.

I had Juvederm injected into the marionette lines below the corners of my mouth about two months ago, and it looked great after the bruising on one side went away. There were bumps, but they weren't visible. This morning I awoke to find that side of my face visibly swollen at the site of the lower injections. I'm sure it's the Juvederm, it feels exactly like the small bumps, the only difference is the size. It is definitely not something else, like a pimple or a boil. What could have caused this? Could it be an infection of the product in my skin, or is it something that's going to go away on its own? I am in excellent health, do not have a compromised immune system or anything else wrong with me. I do sleep with a soft plastic mouthguard that encircles below my lower teeth, and this swelling is directly opposite that area. Might the pressure of the mouthguard against that area have caused this sudden swelling? Anyone ever had this happen?

1/11 update on my review of Juvederm: The swollen area went away and came back a couple of times, then completely went away, as of course, so did the Juvederm. I never found out what caused the swelling. Obviously, I would not have this procedure done again. I also don't think temporary fillers are worth the price or the pain of the shots, given how often you have to have them done. Six months or so ago, I opted to have Artefill done instead. My doctor did it in two stages, a few weeks apart. I am happy with the results, although I think I need a bit more of it for fine-tuning. I've had no side effects at all. Best of all, it's supposed to last about five years.
