I am having Ichithyosis vulgaris...I tried amlactin and couldn't find much difference.. I have used it only for a couple a days so it is too early for a comment ... My scales are small and dark and glued inside the skin..... don't have much of ithcing and not visible as normal ... could anyone tell me the major difference between vulgaris and x link.... and which is the cream good for my dark patches which is glued inside the skin ...
