Atoa Alum stone deodorant stick

What is alum stone?
Alum stone is the pioneer among solid deodorants – a classic that has been appreciated for its pure quality since 1957. This stone is made from a natural mineral crystal and is fully COSMOS NAT certified. What makes it special? It is handmade in France by the last alum master, according to a unique traditional process. Each stone is carefully cut and polished, giving you a truly unique product.
As a solid deodorant, alum stone is not only effective, but also extremely durable: it lasts up to a year! This makes it a smart, economical choice for those who want to live consciously. And the best part? It works naturally against unwanted odours, without chemicals and without blocking your perspiration process – because that is essential for healthy skin.
Key benefits
This deodorant stick combines tradition and innovation. Thanks to its handy holder, it fits comfortably in your hand and is easy to apply. The rounded shape ensures pleasant application, while the stone leaves a thin layer of mineral salts on your skin. This gently regulates perspiration and neutralises odours without blocking the pores.
Alum stone, also known as potassium alum, is a natural mineral known for its antibacterial properties. It helps neutralise odours by combating odour-causing bacteria without irritating the skin. Potassium alum is completely safe, natural and effective – an essential ingredient for fresh, healthy skin.
The stick is environmentally friendly, lasts for almost a year and is also available in a refill format to reduce plastic use. What's more, it is packaged in 100% paper or refillable formats, resulting in hardly any waste. A conscious choice for you and for the planet.
