When my hands are this bad, I try not to use any soap since practically all soaps contain so many chemicals which go directly into my bloodstream. I like to rub on Nutiva Organic Extra-Virgin Coconut Oil from Vitamin Shoppe since coconut oil has antibacterial/antifungal properties and is very good for the skin, if you are not allergic to it. I usually rub some on then wash my hands thoroughly, then dry with a clean towel then rub on more coconut oil then put on nitrile gloves to allow my skin to heal. It usually takes two-three days after a reaction for my skin to heal up.
If its really bad reaction (from soy protein or days after an anaphylaxis event) with open, weeping wounds all over my body, Prednisone does the trick but I try to stay away from Prednisone because of its many serious side effects.
I do have corticosteroids like Betamethason Dipropionate aka Diprolene (liquid "lotion" form) for hands and body and Elocon cream for the face which works like a charm but I question how healthy all these steroid creams are for my body if I use them three times a day every day...so I try to limit my use to times of desparation.
If you have hand eczema, I encourage you to share your stories of what seems to help you most. Hopefully, through reading this and seeing future pictures, you will know you are not alone!
