If you suffer from eczema or chronic dermatitis you should consider using Vaseline.  A smear across the eyes or the problem area creates an impenetrable barrier between your skin and the dust allergen, and unlike creams doesn’t absorb into the skin.  And if you use it before bed, who cares if you look greasy. I’ve used this technique for a while now and it’s miraculous!  Better still, it’s approved for use on eczema by the US National Eczema Society. Try it, and see if it helps your condition.
