You may have seen it in the drugstore deodorant aisle or in ads populating your social media feeds — a new type of deodorant that goes beyond your armpits and is meant for your whole body. The list of brands capitalizing on the trend keeps growing and already includes Lume, Secret, Dove, Old Spice and Native. Ads claim the products can be used from "head to toe" and even from "pits to bits."

But should you reach for all-body deodorants? 

"It's not necessary at all," says Dr. Karan Lal, a double board certified dermatologist and member of the Society for Pediatric Dermatology, based in Scottsdale, Arizona.

Dr. Afton Cobb, a dermatologist with Advanced Dermatology and Cosmetic Surgery in Jackson, Wyoming, says she doesn't recommend using deodorants all over your body. Instead, if you have any areas outside your armpits you want to target, you can try — with caution, she advises.
