We work to keep our formulas as simple as possible, in order to be kind to sensitive skin. Where we can, formulas are free from parabens, fragrance, and soap. In addition, all La Roche-Posay products are formulated with La Roche-Posay Thermal Spring Water at their heart. This naturally mineral-rich water is sourced from a 1,700 year-old spring at the heart of a Medieval French village, and valued for its high natural selenium content, a powerful healing antioxidant with neutral PH levels.
