My dd had a viral rash and when it cleared all her skin seemed to dry and peel. She has never had eczema. I think it is related to the viral skin rash and will clear in a week or so once she sheds the skin. If not then the specialist will be able to help more.

I think watching reactions to foods is a wise course of action for any skin condition, but I would think it most likely this latest flare up is the side effect of a viral rash.
