The eczema is triggered by something he/she eats. If she can identify that, she/he will be sorted. There is a cream and lotion called elocom that works perfectly for kids but it has to be applied very mildly coz it thins the skin. I don't know if the same works for adults.

Let her know the permanent solution is to find out what triggers it and avoiding it. Proteins are notorious, cocoa products (milo, drinking chocolate, bars of chocolate etc... and deep fried stuff like chips)

As euge has said. Find ou about the triggers and avoid thhem like plague. It can reduce with age if triggers are avoided but am not sure if it can permanently go. If you are not sure about what allergens cause it, you can see a doctor bowry at upperhill medical center and she can do allergen tests to determine the triggers that cause the eczema. Many people have different allergens but the main culprits are proteins from meat and dairy products, eggs, plant proteins in soya products as well as different types of beans, and gluten full products.
Another cause that many people ignore is the enviroment we live in. If its a highly congested and dusty area there can be airborne allergens that cause the eczema.
I got to learn all this while taking my child who is eczema prone to dr.bowry

@Dash, thanks. I'll let her know. @Burning Spear - this helps a lot. Asante. Once we help her figure out the root cause then that will be some progress made.
