Both my pied and lemon blast had poor sheds this last go around because I’m struggling with humidity thanks to the house heat running nearly nonstop. My lemon blast in particular looked wrinkly around her neck. I gave her a soak in lukewarm water for about 20 minutes, and added a humid hide to her cage. Once she started shedding I gave her another soak to get any stuck shed loose and she looked fine afterwards. So the wrinkles could be dehydration, poor shed, or both. I think a soak would not hurt and will help rehydrate and assist with the shed.
