Eczema Treatment Care

I have tried everything from the right detergent, the right lotions, I bought a humidifier, and using the right stuff in the shower, I’ve been to three different dermatoligist as well. I heard using a tanning bed might help. Does any one know if this is true? This is my last hope.

my doctor told me i have contact dermatitis on some areas of my back most likely from the harsh chemicals they use to clean the tanning bed ive been using… its the only thing ive been using differently. anyway i want to know, since im going to use a stand up tanning bed from now on so i dont touch the surface, will it iritate it if i tan before the bumps are gone? im on medication for it.
thank you
