Might be TMI but I get really bad B.O. during the summer, and especially after the gym. This stuff is amazing- it's a powder that you rub into your armpits, but absorbs all the sweat AND odour, and leaves a nice, robust, "charcoal" scent. All the ingredients are natural, and it contains no aluminum! Because it's a powder- the bottle lasts forever. Will purchase again when I run out (aka in 10 years)
