Great that you know what it is now, Michael, and excellent that it already seems better. Welcome to the dry skin club
There have been some great posts in the past about soap substitutes for excema-prone skin... I've tried QV, Dermaveen, oats in a stocking, even milk in Nat's bath! The wash that I prefer is the GAIA Natural Baby wash, which I found in my grocery store (and I only use a tiny bit each time in her bath) because it doesn't contain any sodium laureth sulphate (which is the frothing agent that I believe dries her skin out) and only natural oils as purfume.
GL with everything.
