I'm glad that you found something that works for you. I know a lot of people affected in the UK use a product called Oilatum in their baths. I wonder if it's a similar thing.
Ichthyosis-en-Confetti Type 2
Husband, Nathan - 10, Elliot - 7, Oliver - 4, all affected.
I also have an unaffected daughter, age 8.
