You can try to hold it as wet as possible until it heals i made it the same way with my neurodermitia lips

I don’t suffer from it, but my son had eczema. The pediatrician prescribed this insanely expensive cream. I don’t even remember the name of it. It was hundreds (I wanna say $600- it was extreme) even with insurance and we could not afford it. We found an alternative at target that really helped treat the symptoms- cortizone-10 for eczema.

I say he HAD eczema because I was confiding in a friend about how nothing was really clearing it up even after we’d gone to a dr and she asked where his eczema was located- legs, back of knees, inside of his little elbows. She said it could be a dairy reaction. We eliminated dairy and it went away. We haven’t had an issue in over a year and we still mostly limit his dairy now.

I have several kinds of eczema... Depending on what kind depends on what you'll want to do.
Use mild body soaps and gentle laundry soaps. (I use Ivory and Purex since they've been the only ones not to cause flare-ups for me.)
The only lotion I've found to help me is a "Creamy Baby Oil- Angel of Mine" (Angel of Mine is the brand name)
It's really cheap and sold at dollar tree and it works better then the RX my doctor had prescribed.
I tend to order in bulk and just spend the extra to ship it to my home. XD
If you have dead skin build-up on your feet because of your eczema, I suggest doing a foot soak.
1 cup Listerine, 1 cup Vinegar, with 2 cups warm water.
You can double it if needed but soak for about 15 minutes, the dead skin will come off easier. (You can use one of the pumice stones too)
I suggest using the amber-colored Listerine cause the green and blue colored ones can stain your skin for a while.
You can also take daily vitamins/supplements or even allergy pills to help decrease flare-ups as some can be caused by histamines or essentials that might be missing in your diet. Many have luck with quercetin, multivitamins, or vitamin D3, I suggest checking out the National Eczema Association website. They have lots more info that might help you. And I do suggest talking to your doctor before starting any kind of supplement or vitamin.
