My veiled just completed his third shedding in about 5 weeks. After his secound shedding he retained a some skin on the side of his face just below his casque, I put some mineral oil on it a lightly rubbed but it never came off. After this most recent shed, it still hasn't come off and has become slightly larger. I have kept very humid during his entire shed hoping this would come off. I recently rubbed it with a wet, kind of rough wash cloth. Some of it sloughs off, but not nearly all of it and he was getting REALLY pissed. Any suggestions? Are there any products that may help with this? Thanks for your time. David
