I'm a recent newb into the world of natural deodorants. After reading tons of recommendations for primal pit paste on ML, I bought some. I frequently broke out in red, ugly rashes and I stank. Like, stinky stank. A friend who went through chemotherapy for breast cancer told me about Crystal brand deodorant since she had to switch to an aluminum-free when she started chemo. Anyway, it works like a charm. I don't stink and the red rashes and discolored (dark) skin under my arms are gone. It's sold in most stores: CVS, Wallgreens, etc. I bought the roll on (pictured) but it comes in spray and a rock-thingy too.
