This myth hits home a little bit, as I was told this as a child. Now I will say that there are some children who are fortunate enough to outgrow eczema. Or, they are able to avoid flare-ups for years, giving the illusion that they outgrew it. This of course depends on how severe their eczema was to begin with. However, to say that all children outgrow eczema is a myth. I, as well as millions of people around the world can tell you that our eczema is here to stay.
