Do You Really Need Deodorant?

Some guys may  think their sweat doesn’t stink like everyone else’s, but ask their girlfriend or anyone near them in the gym and you’ll probably hear a different story.

The truth is, some people do give off fewer odors than others—but everybody has some sort of trace: “Body odor is determined by environmental factors, like what foods we eat, and genetics. Some people just smell stronger naturally,” explains Robyn Gmyrek, M.D., director of cosmetic dermatology at Columbia University Medical Center. But it’s not the actual dampness that smells. The bacterium that breaks your sweat down into organic compounds is what has that potent stench, she adds.
