Product Insights
The "Alum Stone" by Cosmédiet is a 50 g crystal deodorant composed exclusively of potassium alum, a natural mineral that works by inhibiting bacterial growth and reducing perspiration. Its vegan, additive‑free formulation makes it an eco‑friendly alternative to conventional spray or roll‑on antiperspirants, and it leaves no synthetic fragrance. However, the astringent nature of alum can cause dryness or a temporary white residue on the skin, so users with very sensitive or broken skin should patch‑test before regular use.
Comparative Analysis
Positioned as an all‑natural crystal deodorant, this potassium alum stone offers a chemical‑free alternative to conventional spray or roll‑on antiperspirants, appealing to eco‑conscious consumers seeking vegan, hypoallergenic odor control.
