Can Hylaronidase last in the body, so that when I inject filler into the same spot again years later, it dissolves?

Hyaluronidase is a soluble protein-based enzyme solution that breaks down and helps the body reabsorb hyaluronic acid. It's fast and effective, and it's virtually impossible for Hyaluronidase to still remain present in your skin after several years. It is important to choose the right cosmetic surgeon who is dedicated to the Facial Plastic Specialty in order to achieve the top results.
Hyaluronidase injected into the nasolabial fold is completely gone by 560 hours after injection.
Hello, Thank you for your excellent question. The answer to your question is undeniably no. The hyaluronidase injected into your nasolabial fold 5 years ago was completely eliminated by 560 hours after injection, and very likely before 560 hours. Each drug has a half-life. The half-life is the time it takes for half of the drugs concentration (amount of the drug) to be eliminated from the body after administration. The half-life of a common brand name Hyaluronidase medication is 60-112 hours. A drug is considered to be eliminated from the body in 3-5 half-lives. Taking 112 hours and multiplying this by 5 half-lives is 560 hours or about 23 days. Therefore, without a doubt, by 23 days, the hyaluronidase injected into your nasolabial fold was completely eliminated.
Hyaluronidase To Reverse Filler Injection
It usually only takes 2 weeks for absorption of filler/hyaluronidase to occur, often its much sooner. I suggest seeing an expert for a formal evaluation. Best, Dr. Emer

Hyaluronidase half life in the tissue is somewhere between1-3 days, so within a couple of weeks it is gone. It is not possible that it is still there after 5 years. Any asymmetry after your Juvederm injection can be corrected - so you should go back to your injector and have them take a look. Hopefully they took before photos so you can compare. Sometimes I see patients who think their filler has disappeared but when you compare before and after photos it shows that it is indeed still there. Good luck!
