If you want to smell clean, but don’t want aluminum in your deodorant, there are some out there. Just look for deodorant and make sure “antiperspirant” is not listed anywhere on the label. If you plan to switch, you may want to start in the winter time, when it’s cooler, and when you’re sweating less. You may find when you stop using antiperspirant you’re sweating more than normal, because you’re no longer plugging up your skin and your skin can finally breathe. Be patient, the excessing sweating will calm down.
On a hot day, you’re still going to sweat, but at least you won’t be stinky and won’t be sweating over metal toxicity anymore!
