Review (5/5): No side effects
Very happy with this product. I was having reactions to baking soda and possibly other stuff, which I don't know of. I tried another lavender deodorant which was natural and no chemicals, but something in it was causing red spots under my pits. I have no issues with SmartyPits-Natural/Aluminum Free Prebiotic deodorant (Baking Soda Free). If your sensitive to clean deodorants I would try this first to see if your problems go away. But give it a week or so to heal from the current issues.
