Is expired Hyaluronidase dangerous?

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.

Thank you for your question! Nothing that is expired should be used by an injector and that physician should have long discarded that product! "This answer has been solicited without seeing this patient and cannot be held as true medical advice, but only opinion.
