I really feel for your son. I know how he feels, I have had eczema since childhood.(50 years)
Take the time to read as much on our site as you can to help him build his immune system up as well as possible. I will give you a quick over view here.
Have him eat a well balanced diet. This is important for several reasons. One rich in zinc such as nuts and fish for example. Also A, B, and C vitamin rich foods, such as fruits, and vegetables. Plenty of protein is also needed, such as eggs and high protein meats.
Now, to see quick results to alleviate the symptoms and itching, use our zinc and tea tree lotion from the featured products on this site.
It's what I have used for years and so do my children. Yea, they inherited it from me :(
Really use it at least twice a day until it is under control, then apply once or twice at the slightest sign of an outbreak.
I still use my lotion periodically when I notice a flare up. We do ship internationally, you will see a special link for international orders on the featured products page at the top of the navigation bar to the left.
