Collagen-targeting peptide serum that firms, smooths & boosts renewal
This advanced, peptide-rich treatment is designed to visibly firm skin while supporting natural collagen production for a smoother, more lifted look. Powered by a Gold Pro-Collagen Peptide complex and a growth factor-mimicking tripeptide, it helps reduce the appearance of dynamic lines and improve elasticity. Liquid Oxygen technology optimizes cellular energy for faster repair and renewed luminosity, while niacinamide and squalane replenish hydration and reinforce the barrier. The lightweight texture layers seamlessly day or night, delivering a refined, balanced complexion across skin types.
Formulated for all skin journeys, the AUTEUR Definitive Renewal Serum targets fine lines, uneven tone, texture irregularities, and early signs of laxity. The serum supports collagen I & III synthesis, helps even skin tone, and restores comfortable hydration. With consistent AM/PM use, skin appears firmer and more resilient as radiance increases and surface lines soften. The elegant, fast-absorbing finish makes it easy to incorporate into morning and evening routines without pilling under moisturizer or SPF.
- Who it’s best for: All skin types seeking firmer, smoother, brighter skin; fine lines, early laxity, uneven tone
- What makes it different: Gold Pro-Collagen Peptide + Liquid Oxygen synergy to stimulate collagen and accelerate visible renewal
