From the Definitive Collection. Most serums ask for weeks of patience before showing results. The Definitive Line Serum from Auteur delivers both: an immediate visible smoothing and tightening effect from the first application, and a compounding collagen-building action that improves skin enduringly over time.At the core of this serum is SYN®-AKE Peptide, regarded as the industry benchmark for collagen production and topical skin tightening. It mimics the smoothing effects of cosmetic-surgical procedures through topical application alone. In collaboration with Cyclopeptide-5, it tightens and smooths lines both horizontally and laterally from first contact. A unique complex of multi-molecular weight Hyaluronic Acids ensures hydration reaches every depth of the skin, while Vitamin E and Resveratrol neutralize oxidative damage at the surface. 1 oz. Made in Germany.
