Hi, I am almost 67 years young and have had icthyosis all of my life as have my uncles,,cousins, and some grandchildren. I have tried just about all of the treatments that have come along .....even spending three weeks at the University of Michigan in the derm unit. For a while I was on tegison and I cleared up for a while but in my mind I believe it caused me to have gall stones. I no longer take anything and just go on day to day...........The way I feel .....if the people don't like to look at me.........that's their loss...ohh! on top of having this disease , I also have cronic psoriasis....havve had that now for over thirty years...........
