of course there not helpful what is for eczema theres no cure at the current moment in fact the only thing that can possibly work is immunosuppresive drugs thats it thats why this forum still exists and many people around the world suffer daily from there eczema/dermatitis because the medical world actually has no tools to treat the condition except for topical steroids?
There ways to treat and reduce symptoms. Find a method which makes your life easier yes it will still suck but thats all there is and i guess you can hope that the condition just disappears which is highly unlikely but for a very few people it seems to do much like for some people with eczema and dermatitis it can just disappear and then flare back up out of no were.
but yes lets hope that one of them will also work with our condition but I'm sure it will!
