Hi...by what you quote I feel that your son might be having an allergic condition of the skin called Eczema. The trick of the management is keeping the skin moist and never allowing it to be dry. For this oil
massage and lotions like Oilatum will help.
Regarding cure options - eczema is a sort of
allergy...allergies can only be controlled and can never be cured. But usually kids grow out of it...that is as the age progresses, they become better.
But if the above mentioned
emollient treatment is not working he might require mild
steroid application topically and for this I suggest you see a
dermatologist.
Hope my answer was helpful for you. I am happy to help any time. Further clarifications and consultations on Health care magic are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
