hi.. my daughter is four years old.. and she has been diagnose with ichthyosis since birth.. when i gave birth to her, her skin is reddish and after a week she's scalling all over her body. Then one year later.. her skin in feet up to her leg turns to be normal skin.. its not red skin anymore but more of white pinkish skin and she's not scalling anymore.. when she turns two years old.. her skin in the upper part of her body has turn to white pinkish skin also.. scalling is gone for a while and scalling is always coming back.. what kind of cream can i use for my daughter? thanks
