Can Hyalase enzyme make my nose look slimmer?

Hyaluronidase most certainly will not cause nerve damage. Now it is possible that the needle used to inject the hyaluronidase can hit or pierce a nerve which can cause a bruised nerve and temporary problems.

Hi. Thank you for your question. There appears to be swelling in your photos, and it can take a few days to settle. Also, several sessions are needed to fully dissolve the residual filler. 

There is no danger with using expired hyaluronidase. If there is any untoward effect, it will be slightly less effective. Given it was only 2 months expired, it will probably be just as effective though. I'm not recommending using any expired medications but just want to sooth your anxiety.
