I Was Told That I Suffer From “xerosis” (sp?) And

I was told that I suffer from “xerosis” (sp?) and that this condition was a genetically based disorder that pretty much translates to “chronic dry skin”., for which there was no cure, as that is what the word chronic boils down to. I just have to continually use heavy-duty moisturizers to “manage” my skin....Is ANY of this info that I was given true, or even based in fact? my skin is extremely dry and flaky year round and winter is misery...I currently have six of my ten fingers cracking badly. I work with my hands and that and the cold weather are making my skin painful, hard to use my hands and fingers and often leads to bleeding as well. This effects every aspect of my life...(and not only my hands).......PLEASE tell me I was given bad info by that Dermatologist and that there IS something I can do to fix or at least highly improve my skins health!!.....I am,.......“Desperately Seeking Derma Health”
