Born of the meeting between rainwater and chalky rock, a unique alchemy of minerals and trace elements, La Roche-Posay Thermal Spring Water is an essential ingredient in our skincare products. Naturally rich in selenium, a trace element with remarkable antioxidant properties, it immediately soothes the skin and calms irritations. The 8,000 spa visitors who go every year to Europe's leading thermal dermatology centre for sensitive and weakened skin are very aware that it provides deep relief to people living with eczema or psoriasis thanks to its intense healing powers.
This water with exceptional properties has been the subject of 9 exclusive scientific studies carried out by La Roche-Posay Dermatological Laboratory. These studies have revealed brand new facets of this real wonder of nature: for example, they have allowed our researchers to develop Aqua Posae Filiformis, a revolutionary active ingredient in helping atopy-prone skin, grown in La Roche-Posay Thermal Spring Water and found in Lipikar Baume AP+. And we're convinced: it is far from having revealed all its secrets to us yet!
