There's a tool most of us use to stay feeling and smelling fresh all day: antiperspirant. Americans spend about $2.5 billion per year on antiperspirants and deodorants, and almost all of us adults use these products at least once a day [source: Mintel].
But first things first: Antiperspirants and deodorants aren't the same thing. Antiperspirants plug your pores to stop your sweat, whereas deodorants mask body odor with fragrance. If you want to keep your shirt dry, try an antiperspirant. If you want to cover odor, choose deodorant. Some products contain one or the other; some products contain both. Personal preference will dictate which one's best for you.
