Antiperspirants being harmful is not supported by any evidence or research. It is a common “old wives tale” as they say. If you sweat a lot do not let these rumors keep you from using antiperspirants.

I started using Certain Dri about 10 years ago and my extreme sweat issue has completely gone away. I apply it once ever 6 months or so and use a straight deodorant for everyday. It was a life changer for me.
