It is recommended you go for a food allergy test with your doctor to find out whether is it food or environmental factors which is causing your eczema.

I got very sick when I cut out many essential food and in the end I found that I was not allergic to any of them.

My eczema was not improving. Only after the food allergy test that I found out that my skin condition was due to environmental factors.

Need to moisturise the skin after bath and constantly applying lotion throughout the day.

Found it true on one of my friend's eczema. Just need proper moisturization on the skins throughout.
