I would like to know how long does hyaluronidase stay in your body?

While this is difficult to answer without pictures, it is unlikely that hyaluronidase has negatively impacted your natural tissue. I recommend following up with your injector. Hope this helps.

Hyaluronidase works for about 6 weeks. After hyaluronidase injections, we therefore like to wait 6 weeks ideally before doing more filler injections. Very occasionally, I have flexed this rule but always warn the patient that the filler may be dissolved. Your body also makes natural hyaluronidase, which is why fillers will dissolve away over time.  Hope this was useful!
