Will saline help to fix atrophy caused by hyaluronidase?

1. I had hyaluronidase October 31,2018. The results have been horrific as it HAS taken my own HA. (I only had it injected on the right side of my face and the skin laxity and loss of HA is unbelievable). 2. I had a few drops of filler on Monday, June 17. It really hasn't helped much. Is it safe to get saline after this treatment of filler? 3. Is the damage from hyaluronidase permanent? There are far too many people suffering for this not be a REAL problem that many doctors are dismissing.
