What should I do to prevent more damage of hyaluronidase? How long is the maximum affect?

Hyaluronidase shouldn't negatively impact your natural tissues, however it can take 1-2 weeks for results to settle. If you remain concerned, I recommend following up with your injector. Hope this helps.

Hyaluronidase removes synthetic HA's very well but it also removes natural Hyaluronic Acid from the tissue. This HA is usually replaced my the body in just a few days. You will not lose skin tissue in the area that the enzyme was injected and you should be fine ( absent the injected HA)in just a few days.

I would encourage you to consider Sculptra. It sounds like you could benefit from some collagen boost in that area. Sculptra is a more global approach to volume loss on your face, but it will definitely help this area as well. Over time your body will build more collagen and volume to your face. I would recommend a consultation with an experienced injector. Best of luck! 

Hi maryan37,I would wait until the swelling from hyaluronidase has gone down or after effects have subsided completely. I would consider injecting Sculptra to build up your collagen. It is slow-acting bur shows sustained results. After you achieve your results, you could just have a yearly boost and you'll be fine for at least two years.All the best, Justin Harper, M.D.
