Inside antiperspirant

I recently discovered an informative (and fun) site called the Beauty Brains. where scientists answer your important questions on cosmetics and other beauty products. This week, they posted on Antiperspirant, asking the question, Will covering your body in antiperspirant suffocate you? In other words, if antiperspirant stops you from sweating, then applied to your whole body, would your skin be unable to breathe? What do you think? Apparently, applying antiperspirant only reduces your sweating by 20%, so I don't think it could block all your sweating. And there's no warning on antiperspirant to prevent you from using excess amounts.

What interested me was an explanation of just how antiperspirants work. Apparently, aluminum salts in antiperspirant, when mixed with water (sweat), swells sweat glads and block more water from coming out. Who knew? Not me, in any case.
