DS2 has eczema quite badly on his legs and feet, less badly on his arms, hands and face. We've gone through a lot of emollients and bath stuff before we've found the combination that works.
The best solution we found is Fucibet for really bad flare ups (where the skin is very scaly and thickened), Eumovate for milder flares and Hydrocrtisone 0.5% for the odd patches on his face. We use Dermol bath emollient and Dermol lotion to moisturise him, we also cover him in a thick layer of Dermol lotion before he gets in the bath to stop the water drying him out.
He reacts to perfumes in toiletries so we only use Simple shampoo on him and wash his hair just before he gets out of the bath so he's not sitting in the suds. We also only bath him once a week because baths are very drying on their skin, even with all the stuff in the water.
We use Ecover liquid for laundry, I put in about half of the amount the bottle suggests and use the super rinse setting on the machine. Switching to Ecover from Non Bio has helped a lot but ti does take several washes to get rid of any allergens from the old powder, apparently.
I was recommended Pure Potions Skin Salvation balm by someone on MN which is made of Olive oil, Hemp oil and a few other things but it's completely natural with no petro chemicals etc. I first tried it when he was having a bad flare and it seemed to make it worse but the Fucibet/Dermol combo got it fairly under control and I tried it again. This time it's been brilliant. I've been using it for 3 weeks and have only had to use the steroids once in that time. He's never been that long without steroids (previous record was about 3 days, I think) so I'm converted!
I would definitely ask your gp about trying different creams and bath stuff. Mine said they're very cheap so they don;t mind prescribing them.
