I used to have very bad eczema under my arm pits leaving them red raw which was very uncomfortable for me. I didn’t realize at the time, but it was due to the deodorant sprays I was using under my arms which was causing the eczema and making it worse. I started to use the Alum stone under my arms and within a month all the eczema was gone. Remarkable! What a great product, would recommended to everyone!
