The Serum which contains at least 99.4% naturally derived ingredients has also an ultra-high concentration of GSM10 ® and ProGR3 ®, two exclusive patent-pending active compounds that help slow down skin aging. The GSM10® in The Serum is made from grape marc that comes directly and exclusively from the Perrin family's land and is also eco-extracted by natural means, directly in the field by Le Domaine's farmers. From the very first use, The Serum boosts skin by creating a unified, refined skin texture. Within 28 days, The Serum produces an anti-wrinkle effect and an overall anti-aging effect. Revitalized and protected, the skin is firmer and brighter, appearing visibly younger with a youthful glow. Its ultra-silky penetrating texture leaves the skin intensely plumped-up. It is ideal for all skin types. In its Luxe version, the stoppers are made of oak cut from the scraps of Famille Perrin wine barrels.
