Active water for the skin: seeping slowly through chalky beds from the Turonian period, the thermal water of La Roche Posay is drawn from depths of 30 to 80 metres. With a low mineral content, it is bicarbonated, calcic, silicated water containing selenium. Its extraction temperature is 13°. It has anti-inflammitory, anti-pruriginous, healing and anti-free radical properties. Thermal water lays a silicated calcic dressing on the skin that regenerates it.

This water is an essential component of the La Roche Posay pharmaceutical product range.
