There is currently no cure for eczema.
Many children will grow out of the condition but if you are born with the predisposition to develop the condition you will always have it in your system and it may be triggered at any time.
Many people who have eczema as a child and grow out of it find that they continue to have dry skin into adulthood and may remain allergy prone. Exposure to a substance they are sensitive to may trigger a flare up of eczema even though they have not experienced any symptoms for years.
Study into eczema continues with the ultimate goal being to find a cure. One can only hope that in the not too distant future a cure will be found.
