Containing our highest concentration of Sève Bleue des Océans yet, this hardworking serum is ideal for intensely dehydrated, thirsty skin. Enriched with Mediterranean Padina extract, this alga reactivates skin hydration and reinforces cell cohesion—to limit the loss of water as well as essential nutrients. With the ability to penetrate the top layers of skin and release key nutrients deep into the skin’s dermis, this light formula delivers an instant boost of hydration whilst protecting the skin’s delicate moisture barrier—for dewier, more glowing skin.

Best for: Dry & Ageing Skin
