There are lots of things you could try.
Defintaly moisturise more to try and keep the dryness at bay, and to try and stop the itch scratch cycle forming. You could try hydrocortisone cream on flare ups, tho sometimes u need something stronger. be aware that the skin can get infected, so if its goes to a yellowy crust or starts weeping, then go see a gp to get it seen to, as broken skin is easily infected and not as easy to shift.
Bath daily, but also add a bath addictive for ezcema (there is a large range, people have menti0on aveeno, also oilatum(normal, plus, unfrangenced) , eurcerin (5 or 10%), balneum,
whisked up aquous cream. It can be a case of trial and error to find one that works. same as with the emoillants, its all trial and error.
I find that a light lotion (dermol500) works better on my dd1, whilst dd2 needs something more intensive. DD1 responds well to hydrocortisone OINTMENT, whilst dd2 needs the cream version.
So as you can see, its all confusing and it is hoping you find a combination that works well for you ds soon.
