Advanced peptide serum that reactivates collagen & restores firmness
The AUTEUR Definitive Collagen Activator is a high-performance serum designed to restore firmness, elasticity, and youthful volume by reawakening collagen and elastin production. This lightweight, silky formula features Gold Pro-Collagen Peptide, a powerful signal peptide that helps stimulate collagen I and III synthesis for improved skin strength and density. A bioengineered Growth Factor complex supports cellular repair, while Hyaluronic Acid and Niacinamide replenish hydration and brightness. Skin appears smoother, lifted, and more refined with every use.
Created within the AUTEUR “Definitive” collection of high-active formulations, this serum targets visible laxity, fine lines, and fatigue in the skin. Liquid Oxygen technology boosts cell metabolism for optimized renewal, while the inclusion of antioxidants like Ergothioneine helps prevent further collagen breakdown. The result is skin that looks revitalized, supple, and resilient. Suitable for all skin types, this potent treatment layers seamlessly under moisturizer or SPF both morning and night.
- Who it’s best for: All skin types showing signs of loss of firmness, elasticity, or early wrinkles
- What makes it different: A dual-action Gold Peptide and Bio-Placenta complex that targets collagen and elastin renewal at the cellular level
