Deonature Men Crystal Stone Antiperspirant – 100% Natural Alum, Fragrance-Free 60g [Alcohol-Free]

Deonature Men Crystal Stone is a stone-type medicated antiperspirant deodorant designed for men who want maximum sweat and odor control with the simplest, cleanest formula possible. Made with 100% natural alum stone (myōban), this additive-free deodorant works directly at the source of odor to keep underarms dry, fresh, and comfortable from morning until night.

Unlike stick or roll-on deodorants, the crystal stone is activated with water and applied directly to clean underarms. The alum adheres firmly to the skin, forming a thin invisible layer that tightens pores, inhibits odor-causing bacteria, and neutralizes ammonia odors—without clogging pores or irritating the skin.

This formula contains no fragrance, no coloring, no preservatives, no alcohol, and no menthol, making it ideal for sensitive skin and for men who prefer a completely neutral, no-nonsense solution. It dries quickly after application, leaves no stickiness and no white residue, and allows you to get dressed immediately.
