I have Eczema. Pretty bad case but now under control.
My advice to most of you is instead of generalizing and basing things on heresay , get an allergy test done.
I did mine twice and found out i'm highly allergic to Chicken / Eggs and Chocolate for food , Rubber and cockroaches (droppings/urine etc) for contact surfaces.
I avoid them nowadays so my sources of protein are mostly seafood and meat now.
