A serum that helps to replenish moisture in the skin by using a unique complex of low and high molecular weight Hyaluronic Acid. The staggered molecular weights of the Hyaluronic Acid are designed to help promote multi-depth hydration on both the skin's surface and in the epidermis. Enriched with replenishing Provitamin B5, the skin's elasticity appears improved as well as feeling and looking softer than before. Hyaluronic Acid Low Molecular Weight Hyaluronic Acid is a lightweight, versatile hydrator that attracts and binds 1,000 times its weight in water. Low Molecular Weight Hyaluronic Acid is such a tiny molecule, it's able to penetrate deep into your skin and replenish moisture from within. Hyaluronic Acid High Molecular Weight Hyaluronic Acid, due to the larger molecule size, this Hyaluronic Acid sits on top of the skin, forming an invisible shield that traps moisture. This helps reduce moisture loss from stress, heat, extreme cold and environmental factors. HOW TO USE Apply a few drops to damp skin before creams. Use morning and night. WHAT IS FARSÁLI PRIVÉ?
