Desodorante piedra de alumbre mineral

This deodorant stone is a mineral-based hygiene product composed primarily of potassium alum and water, offering a high-purity, minimally processed (NOVA 1) formula that works by forming a thin temporary crystal layer to inhibit bacterial odor. It appeals to consumers seeking a spray‑free, zero‑waste alternative, as it contains no synthetic fragrances, preservatives, or added chemicals beyond the aluminum salt. However, the presence of potassium alum may cause irritation for individuals with sensitive or aluminum‑allergic skin, and its efficacy may be lower for very heavy perspiration compared with conventional antiperspirants.
