My DD9 has eczema, however it is related to an unknown/undetectable allergy (which I can pinpoint to certain dairy products and certain lollies but according to allergy tests, she isn't allergic to dairy...) anyways, over the years we have tried every single product on the market, including steroid creams... I have to say- the absolute best thing is PawPaw cream.. It's a red tube or you can buy it as a container that you can get almost everywhere, including Target. It's the only thing we use and it gets rid of it (if we catch it early)- within the day... If we miss the early signs, it can take it 2-3 days, but it is by far the best stuff.. And it's cheaper because anyone in the house can use it.
Hope this helps.
