Yes. FerryBerry is a natural deodorant, and all of our deodorants are aluminum-free. Now, if you are asking about antiperspirants, well, they on the other hand, use pore-clogging aluminum to artificially reduce sweating. The aluminum contained in antiperspirant acts as a plug on your body’s sweat ducts and prevents you from sweating and releasing other byproducts of sweat. But remember, sweating is natural and is one of the ways your body cools and detoxifies itself. Our FerryBerry deodorants, for both men and women, works with your body’s natural chemistry rather than against it.
