Mineral Crystal Deodorant Stick

A Cosmos Natural Cosmetics certified natural deodorant made from pure potassium crystal for effective, long-lasting odour protection without aluminum chlorides. Housed in sustainable cork packaging, it offers a skin-friendly and eco-conscious alternative to conventional deodorants.

The Story

Crafted with simplicity, sustainability, and performance in mind, Biork™ combines the natural power of potassium alum crystal with environmentally responsible design. The mineral crystal works by inhibiting the growth of odor-causing bacteria, delivering reliable all-day freshness while remaining gentle on even the most sensitive skin.

Unlike many mainstream deodorants, this formula contains no aluminium chlorides. Instead, potassium alum sits on the surface of the skin, helping create an environment where odour-causing bacteria struggle to thrive. The result is freshness that feels remarkably clean and understated.

The innovative cork packaging is completely plastic-free and helps support CO2 reduction while preserving Portugal’s biodiverse cork forests — one of Europe’s most valuable natural ecosystems. Long-lasting and refill-free, a single crystal can last up to a year or more with regular daily use.
