Hello,
Welcome to healthcare magic.
From your history, your daughter may be having
ichthyosis vulgaris( an extreme form of
dry skin) or a topic
dermatitis ( a type of skin eczema associated with nasal allergies and/ or wheezing in self or family) . Both the conditions have a familial tendency and can be passed from parents/ grandparents to children.
Use a good cream based moisturiser every 3 hours.
Apply an oil like coconut oil or
paraffin oil on damp skin within 3 minutes of bath to trap the moisture.
Give lukewarm water baths and avoid hot water.
Use a soap free cleanser like
cetaphil cleansing lotion for bathing her and avoid harsh soaps. Use very minimal cleanser.
Avoid woolen fabrics and instead use 2 layers of cotton to keep her warm in winter.
Increase intake of oily fish.
Hope these help you.
Take care.
