A deodorant is a substance applied to the body to prevent body odor caused by the bacterial breakdown of perspiration in armpits, feet, and other areas of the body. A subgroup of deodorants, antiperspirants, affect odor as well as prevent sweating by affecting sweat glands.

Crystal deodorant stones contain a naturally occurring form of aluminum made up of molecules too large to be absorbed by the skin. This helps make these products effective at preventing bacteria-causing odor found in sweat from developing, rather than artificially clogging pores as antiperspirants do.
