There are over the counter creams, a good pharmacist would be able to recommend one. I have eczema on my hands and legs - I use E45 a lot because it doesn't irritate the skin. Norwegian hand creams tend to be really good if your hands are really dry but check you get the ones with no fragrance. The main thing - unfortunately- is to not use any products that have perfumes - that includes soaps, bubble baths, shower gels as that will aggravate the eczema. It makes for a very boring bathroom shelf, but definitely helps. I treat myself occasionally to a "smelly" bubble bath but not very often or I start scratching again!! How ladylike...not!
I never found an over the counter cream that worked, and to get the eczema off my hands i had to use REALLY strong steroid cream and I even had moisturized prescribed by the doctor which was the only thing that got the eczema off.
The usual cream I had for my legs was quite a high strength Eumovate, but you can get a lower strength one over the counter. They're called hydro-cortizon creams ... or something like that.
E45 is alright for keeping moisturized. I can't for the life of me remember the name of the moisturizing cream that i used on my legs. I remember being told that you can't use too much moisturizer, so if you're still dry then put some more on.
