Deodorants are preventative substances applied to the body to affect body odor caused by bacterial growth and the smell associated with the bacterial breakdown of perspiration in armpits, feet and other areas of the body. The latest clean beauty trends feature products that are free of aluminum, parabens, Propylene glycol, and more harmful chemicals. 

A subgroup of deodorants, antiperspirants, affect odor as well as prevent sweating by affecting sweat glands. Antiperspirants are typically applied to the underarms, while deodorants may also be used on feet and other areas in the form of body sprays.
