As an intensely hydrating SOS for your skin—the 7-Day Hydration Treatment combines nutrient-dense Sève Bleue des Océans and Thalgo’s Micronised Marine Algae with a biometric NMF complex. This ingredient is composed of 10 potent molecules that are designed to perfectly mimic the skin’s natural moisturising factors—resulting in more hydrated, resilient skin. Additionally, this thirst-quenching formula also contains a low-molecular weight hyaluronic acid to deeply penetrate the skin’s surface, instantly refreshing and plumping skin. Ideal for those who enjoy a lightweight serum, this 7-day series is concentrated care for your complexion.

Best for: Dry & Ageing Skin

Use every day for 7 days by applying a half dose (1 vial = 2 applications) to freshly cleansed skin morning and evening. Close the vial after use by using the resealable upper section. Follow with your preferred Source Marine moisturiser.
