Can hyaluronidase cause atrophy (depressions/indentation) in the skin?

I had Belotero injected into the tear troughs that causes excessive swelling. I had them dissolved, but now I notice that my eyes have hollowed out, depressed areas that look like indentations. I was under the impression that hyalase would only dissolve the fillers and not cause significant damage to myself. How long will it take to fill in again? Or will it never come back? I had the hyalase 1 month ago and no improvement.
