Q: How do you pronounce S’eau Prima? What’s the significance of the name?

A: The name is pronounced “sōh” (rhymes with glow) “Preema” (think of prima ballerina or prima donna). The “S” represents Skin, at the core of the brand, “Eau” translates to Water in French, and Prima is defined as “first” or “lead,” which speaks to The Foundational Mist as the first layer of Skincare, as well as the role we believe women should play in all aspects of life and society – it’s time for women to lead.


Q: Why do you call it The Foundational Face Mist?

A: The Foundational Face Mist is the ideal first layer of skincare because, among other things, it balances the skin’s pH level and restores the skin to a healthy state, allowing it to better absorb your other skincare products’ active ingredients, be that moisture, antioxidants, or other acids. In this way it lays a foundation for the rest of your skincare regimen (not to be confused with foundation makeup!).
