Will Hyaluronidase Cause Bruising Like Juvederm?

Any time you put a needle into the skin there is a potential for bruising.  Increased bruising can be seen with patients who have recently taken aspirin, ibuprofen, and most herbal supplements, (st. johns wart, ginko, garlic).  Vitamin A and E are also known to cause bruising.

That being said, the risk of a bruise with this treatment is less as there should be less needle sticks.

I would tell your doctor the situation; review the medicines, vitamins, and herbal supplements you are taking, and together make a plan.

Less likely. The volume needed to correct the problem is very small. Which means the likelihood of a bruise is less as well.
Get it done (Hyaluronidase) by someone who has experience with it. If you do end up looking bruised and do not want to explain it to your co-workers, tell them you had some dental work done.
Don't be disheartened. Juvederm is a great product. It just needs to be done correctly and can give you a great result.

Hyaluronidase can cause bruisng just as any injection has the potential. It is sometimes added to local anesthetics to help the product spread through the tissues. However, some surgeons are reluctant to use it because they believe it may cause a greater tendency to bleed.
However, in my opinion, it tends to be less because it generally requires less injections to place the material as it tends to spread on its own.
