Crystal Deodorant
A crystal deodorant is a natural deodorant based on mineral salts, usually ammonium alum (also potassium alum). It works by leaving a thin mineral layer on the skin that inhibits the growth of odor-causing bacteria without clogging pores.
Properties of crystal deodorants:
✔ Natural: Contains no synthetic fragrances, parabens, or aluminum chlorides.
✔ Odor-neutralizing: Kills bacteria instead of just masking odor.
✔ Long-lasting: A crystal deodorant can often last for months or years.
✔ Skin-friendly: Non-irritating, making it suitable for sensitive skin.
Best Quality
Biork uses a high-quality crystal stone naturally produced in Central America. The stone is milled from a single piece, not glued together like most "cheap" stones from Asia. Crystals generally consist of three distinct parts: the base, the heart, and the outer shell. Underneath the base is usually a collection of impurities. The heart of a naturally sourced potassium alum stone is solid and pure. This is where the crystal is most valuable. The outer shell is very fragile and therefore cannot be used as a deodorant crystal. Biork uses only the heart. Our stone is therefore crystal clear, unlike those from Asia, which tend to appear cloudy. This means our stone lasts longer and won't crumble over time. The trend toward mineral or crystalline deodorants continues unabated. More and more people are complaining of skin irritation when using deodorants with artificial ingredients.
