The unique selenium-rich Thermal Spring Water at the heart of a small village in central France called La Roche Posay flows through La Roche-Posay’s skincare formulas.

La Roche-Posay Thermal Spring Water is the result of rainwater flowing over vast expanses of limestone rocks, natural reserves of the element selenium, and deep water over 20,000 years old, flowing through the deep sands of the Cenomanian period. Of the highest purity, and with an almost neutral pH, La Roche-Posay thermal spring water is protected from all pollution and not treated in any way until safely packaged.

The complexity and rarity of La Roche-Posay Thermal Spring Water lie in both the stability of its ingredients, which maintains its high selenium content and the physiological balance of the skin. Selenium, a powerful anti-oxidant protects cells from oxidative stress (one of the causes of skin aging) and plays a fundamental role in cellular preservation. It is used to treat numerous skin problems.

With anti-inflammatory and anti-free radical properties, thermal spring water helps treat certain serious inflammatory skin conditions when used as a therapeutic complement. It also helps to fight skin aging, and its dermatological benefits are recognized by the highest scientific and medical authorities.

La Roche-Posay treatments are formulated according to two fundamental principles: high standards and dermatological safety.
