My 6 year old has been suffering from eczema since she was 1. How long does it take for children to outgrow eczema?

You may want to adjust your son's diet too to help him healing faster. Eczema is linked to deficiency of good bacteria in the gut. To overcome this problem, consume prebiotic such as Arabic Gum and probiotic (i buy brand LactoGG) probiotocs are the healthy bacteria while prebiotics are 'food' that help growth of the bacteria. Reduce or replace white sugar intake, and avoid preservatives,food coloring,junk food.
