Why have I tried so many products but still with ichthyosis?

Many ichthyosis patients have tried so much moisturizing products or creams to treat and care for the ichthyosis skin, but the effect is not ideal. Why?  

First of all, we need to understand that the #scales accumulate on ichthyosis skin caused by excessive metabolism of skin epidermal cells, premature aging, and unable to peel off naturally.  Its internal cause is to lie in skin epidermis, dermis and so on abnormality.  

 Only external skin care products using(such as urea ointment, glycerin and other moisturizing skin care products, etc.) can only play to temporarily make scales invisible, but can not prevent the continued generation of scales from the inside, and fish scale patterns, ines will not disappear.
