Hello,
Eczema is a form of chronic dermatitis (rash).Allergic reaction is one of the important
causes of
eczema. Allergic reaction can occur to strong soaps, Solvents, chemicals, certain foods, food additives, plants, metals, cosmetics, even urine and faeces of some animals (dust mites).
But in case of ocean water, according to the British Association of Dermatologists, there is considerable evidence that salt water baths may help some patients with atopic eczema.
Hope it helps.
