I'm at day 24 after strong dose hyaluronidase. At day 14 I posted up on here, in despair. There didn't seem to be any improvement or rebound to my skin. It had massively hollowed out. Most of the responses I got from this reddit group were that the improvement I see at day 14 is as much as I'm going to get. Wrong! I have noticed a positive change last morning and today. So for anyone who thinks that there is no way back, I'd wait till around the 11 or 12 week mark to conclude that.
Anyone who has passed the 3 month mark and is still deflated. I know it must leave you scared to try anything, but perhaps you could take little steps towards skin recovery. Maybe a weak topical, then something stronger, perhaps microneedle a small area then a bigger area. So far what people have said has helped them: Tesoro, GHK Cu, emu oil, threads, microneedling, meso, tretinoin
I was in a dark and miserable place these last 3 weeks, so I can relate to the dispair felt by those who think their skin is not going to recover. I'm not recommending the treatments above, but just trying to give hope. If you're feeling down about this maybe a cautious approach can help you to establish if there is anything in particular that might help you.
