Caudalíe's Premier Cru anti-aging serum is made with a formula based on a high concentration of hyaluronic acids (low and high molecular weight), which provides immediate and intense hydration to the skin. This serum is enriched with tensor sugars that provide an immediate effect that is visible after 3 minutes and lasts up to 6 hours. The perfume of the Premier Cru Serum is made up of Damascus rose extract, rose petal essence, geranium essence, rose absolute, violet leaf absolute, white cedar essence and Siamese benzoin absolute. Its formula contains: Viniferine : Caudalíe's patented ingredient derived from vine sap, which performs an exceptional anti-spot action, more effective than vitamin C. Hyaluronic Acid: Produced through biotechnology, it continuously smoothes and hydrates the skin's surface. TET8™ Patented Technology (Caudalie x Harvard Medical School) : revolutionary technology that combines Resveratrol from grapevines and Honokiol (green extraction from Magnolia) to stimulate the activity of the TET enzyme and act on youth proteins to correct 8 age markers. It is recommended to apply the Premier Cru Serum morning and night on the face, neck and décolletage, before the cream. Maximize the anti-aging effectiveness of the Serum by applying the cream afterwards. Store in a cool, dry place.
