Have been to 3 dermos. over the years for atopic dermitis. All recommended Cetaphil soap & lotion. I buy the Cetaphil cream (in a big green & white jar). It's often on sale at Walgreen's for about $8.00. When your hands become raw, cover them with the cream and wear white gloves (if you can find them anymore) at night.
I've heard other docs. recomend Dove. Nancy is right -- could well be the soap.
