are you the DIY type? you can make your own eczema ointment/oil/cream to try in lieu of otc stuff that may or may not help you. I'm suggesting trying 100% natural and chem free so research the properties of the following:
oils/butters to consider:
organic virgin coconut oil, organic raw shea butter, organic raw cocoa butter
herbs to consider:
chamomile, burdock, chickweed, aloe vera, neem, calendula, turmeric, borage (seeds and/or flowers), lavender, comfrey, witch hazel, marshmallow, nettles
its as easy as finding a few of these herbs locally and letting them steep or infuse in some kind of gentle carrier oil (grapeseed is one of my faves but you can mix n match as you see fit)...you can then apply it topically like a herb packed moisturizer.
if you feeling fancy you can add a wax of some sort and a natural butter (shea, kokum, cocoa) then you can turn it into a salve or balm.
