I would try to feed her a fuzzy every five days to get her weight up.

For the skin I would add moss to the hides and mist it each day when you mist the tank. This will create a micro clim in the hide making it more humid than the rest of the tank. I regualrly keep moss in my hides for my healthy bp and have great sheds. If may take a few sheds for the skin to really come back.

Be patient and good luck.

Good rescue!
