Deodorant and antiperspirant are two different products. If you’re just concerned about odor, deodorant is the way to go. The distinguishing difference between deodorants and antiperspirants is that the latter contains aluminum chloride, an ingredient used to block sweat. I think if you’re a heavy sweater, using antiperspirants is better way to go.
Sometimes a single swipe isn’t going to cut it. To avoid an unexpected sweat sesh (like, when you’re in the middle of a meeting), apply a generous amount of antiperspirant to your entire underarm area to ensure all sweat ducts are covered. You have to cover the sweat glands thoroughly.

Got itchy pits? Women with eczema or other sensitivities should stay away from heavily-scented deodorants because they can irritate the skin. Before using it under your arms, test the product on your wrist. Or, try a fragrance-free deodorant.
