They are surface acting agents that reduce the flow of perspiration and absorb moisture. In contrast, deodorants employ antimicrobial agents, that while safe as used, could be tee-ed up as much more dangerous than the antiperspirants.

Clearly, there is something better about our environment or lifestyle that is positively overwhelming the very negative effects of higher body weights.
