How long will this cannula wound last? (Photo)

I can take a couple days to settle down. This is nothing to worry about. Somewhat larger cannulas are used with Bellafill but they all heal up fine. If it becomes tender or red, discuss with your provider. Bellafill is a safe, long lasting filler. I place the filler deeply with cannulas as well.

It's hard to tell from the picture if this is a hole from the injection site, or swelling, or possible small amount of Bellafill product that was injected to close to the skin as the cannula was being pulled out.    I would wait a week or two to see if the bump or swelling goes down.   If the swelling remains and stays firm, it could be the product which can be reduced by a small amount of steroid injection in the bump.

Congratulations on making the decision to get one of the best fillers there are.  Hopefully you will like the results.  The cannula entrance points will usually be gone in a day or two.  They are simply large needle holes that your body will repair within days.I hope that helps.Best regards
