Originating as pure rain mixed with sea-spray rich in mineral salts, Avène Thermal Spring Water makes its 50-year journey through the Cévennes Mountains in Avène, France. It gradually becomes infused with trace elements and silicates, and comes in contact with an ancient microorganism Aqua.Dolomiae, which was first identified by Avène in 2001. This remarkable biological property combined with the well-known mineral properties of Avène Thermal Spring Water ensures gentleness and tolerance, creating a unique double signature that does not exist anywhere else in the world. Over 150 stringent biological, pharmacological and clinical studies have clearly demonstrated the soothing, softening and calming benefits of AvèneThermal Spring Water. Avène Thermal Spring Water is representative of our dedication to protecting Humankind and the environment. This one-of-a-kind product preserves the Thermal Spring Water under sterile conditions throughout its use, thus preserving its soothing and anti-irritating properties. With each spray, the Water is released completely intact, pure and clear, as if you were drawing it directly from the spring. After packaging, the spray bottle is covered with a hermetic, tamper-evident seal. These precautions provide a major advantage for sensitive skin, anywhere, anytime.
