This 4 fl oz spray relies on potassium alum, a natural mineral salt, to form a protective barrier against odor-causing bacteria rather than blocking sweat glands the way traditional antiperspirants do.
It's fragrance-free, non-sticky, and formulated without aluminum chlorohydrate or parabens.
The label suggests spraying under the arms — or even on the bottoms of feet or inside shoes — for up to 24 hours of odor protection.
