When you walk down the deodorant aisle at the grocery store, you might feel overwhelmed with where to start. First, remember that deodorants and antiperspirants do different things. Deodorants can get rid of the smell, but not the sweat. They are alcohol-based and help keep bacteria from growing on your skin. They may come with a perfume or smell to mask any body odors. Antiperspirants on the other hand don't touch the smell. They contain aluminum-based compounds that actually block your sweat pores, keeping the moisture to a minimum.
"Antiperspirant decreases the amount of sweat that reaches the skin. A lot of them contain aluminum salts, and what those do is form a plug, and it prevents the sweat from reaching the surface of the skin, and that helps keep you dry," Dr. Zeichner told Fox News. "Now, totally separate from that are deodorants, and those are basically products that have masking fragrances. When you go to the store to purchase a product, most are antiperspirants and deodorants." Look for a product that does both if you want to cover all your bases.
The trick with antiperspirants is to apply them at night. If the over-the-counter options aren't doing the trick, ask your doctor about a prescription antiperspirant.
