You can make one using paper towels, moss, or any other material that absorbs water well and just put it under a hidebox in the cage. If it looks like loose skin sometimes it may not come off as you rub it...if you look closely does it look to be discolored scales? If you're really worried about it you may just want to take it to a vet just to get it checked out...although they are quite expensive. I know the LSU vet school deals with reptiles...I have an appointment to go to on Tuesday, but I dont really think it should be a problem that should involve a vet...its most probably just shed and just give it some time to come off naturally.
I got a couple balls, a chameleon, a water dragon, and some leapord geckos.
