Are you saying that you use deodorant? I would advise against it, the stuff is pretty much always highly toxic.
Bad smells can be toxins; OR it can be bacteria. Maybe a combination.
People have come up with creative ways to stop the bad odor, such as baking soda, corn starch, Colloidal Silver , etc.
But most people find that when they cleanse their body and eat healthfully, they no longer have Body Odor s. I don't use deodorant and I don't have smelly armpits.
