The dimpling is pretty common. I wouldn't worry about it too much. It's probably dryness - not dehydration, just dry scales. As long as she has access to fresh water and is drinking and eating well, it shouldn't be an issue. Ideally, these guys like to soak pretty regularly. Keeping a cage as wet as they like is not easy to do, while keeping it clean and fresh. The only suggestion I have would be to soak her when she's in shed (after the blue phase) if she has any issues shedding. Sometimes, especially after dirtying their cages, I soak mine also.
