M.M.
Summer 06 edition of Allergy and Asthma publication did an article on the links to eczema and commercial bath bars. I have skin issues all my life. Changing to all natural soaps (real soap) and natural laundry soaps made a significant improvement. Reducing the water, change in soap products (dove did the complete opposite for me as well as all the creams from my dermatologist) scaling down to absolute basic natural ingredient product that touch my skin and wash my clothing was the biggest and the simpliest relief.
I have also been able to almost completely remove using lotions out of my routine by making these changes -- and best yet -- no more itching!
While I am a believer in traditional medicine and the great products available at the pharmacy -- after many years of trying to resolve a skin problem, I found simplicity to be the ticket.
It would not hurt to start there first then work your way into the steroid creams if necessary.
Good luck
