Pierre d'Alun deodorant, made from natural alum stone, is a popular alternative to chemical-laden deodorants. It works by creating an invisible salt layer on the skin, preventing bacteria that cause odor. Hypoallergenic and fragrance-free, it's ideal for sensitive skin. Simply wet the stone and apply it to clean skin for long-lasting freshness. Unlike commercial deodorants, it doesn’t block pores or leave stains. Have you tried it?
