Oh, deo. It’s inspired '90s garage-band tunes and a vast variety of olfactory experiences. Who can forget Sex and the City's Aidan insisting on hoarding five separate Speed Sticks? Much like foundation and SPF, the deodorant is a mysterious creature.
Let’s start by breaking down the difference between antiperspirant and deodorant. “Antiperspirants are over-the-counter deodorants that contain FDA-monograph-approved ingredients that interact with the sweat glands to help stop perspiration,” explains cosmetic chemist Ron Robinson of Beautystat.com. “Deodorants are products that work to mask underarm odor. They often contain a fragrance or perfume, along with an active ingredient called triclosan that is commonly used and works to prevent bacteria from growing, which in turn helps prevent odor.”
