How long will this cannula wound last? (Photo)

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.

I hope that helps.
