Auteur Definitive Collagen Activator Serum

Build collagen. Stop its degradation.

Most collagen serums address production. This one addresses both sides of the equation simultaneously. Next-generation peptide technology mimics the skin's natural collagen synthesis pathway to rebuild structure, while a targeted antioxidant and anti-inflammatory complex protect that structure from the environmental and biological forces that break it down. 1.0 oz.

Two Mechanisms. One Serum.

Build-Peptides mimic the skin's natural collagen production to firm, refine, and improve elasticity

Protect-Antioxidants and anti-inflammatory agents inhibit degradation and reduce inflammageing

With Daily Use:

Firmer. Smoother. Brighter. More resilient.

As fine lines and wrinkles fade with consistent application, skin becomes measurably smoother and healthier. Radiance increases as collagen production compounds and inflammation is reduced. A brighter, more resilient natural state emerges over time.

Benefits:

Reduce wrinkle depth
Refine pores and regulate sebum
Protect against collagen degradation
Optimize collagen and elastin synthesis
Advanced antioxidant protection
Activate transforming growth factor beta (TGF-β)

The Formulation: 

Growth Factor Tripeptide and Collagen Peptide Complex form the collagen-activating core of this serum, working together to stimulate Type I and Type III collagen synthesis through pathways that mirror the skin's own production process. The result is structural improvement that compounds with daily use. Simultaneously, a curated antioxidant complex neutralises free radicals from UV and environmental exposure, bio-optimised agents support cellular health, and anti-inflammatory actives reduce senescent cells to address inflammageing at its source.

Epidermal Growth Factor: Signals the skin's own repair and regeneration processes. Accelerates cellular renewal, supporting the restoration of healthy, resilient skin particularly in dry or sensitised conditions.
 Hyaluronic Acid: Draws and binds moisture to the skin for immediate and lasting hydration. Visibly plumps fine lines and restores a supple, well-hydrated appearance from first application.

Antioxidant Complex: A curated blend that neutralises the free radicals generated by UV exposure, pollution, and environmental stress. Protects the collagen being built by the peptide complex from oxidative degradation, preserving the structural improvements made with each application.

Bio-Optimised and Anti-Inflammatory Agents: Reduce senescent cells that accumulate with age and drive the chronic low-grade inflammation known as inflammageing. Address skin ageing at its biological root, improving overall skin health rather than only targeting visible surface symptoms.

Visible results:

Firmer: Collagen synthesis stimulated. Structure and elasticity rebuilt over time.

Smoother: Fine lines and wrinkles reduced. Skin texture visibly refined with daily use.

Brighter: Radiance increased. A healthier, more luminous natural skin state.

Resilient: Degradation inhibited. Inflammageing addressed at its biological source.

How to use:

Use morning and/or evening, up to twice daily as your daily serum under cream.

Apply to face, plus an extra pump for neck and décolleté, letting it fully absorb before cream or SPF.

Especially powerful in the daytime to support skin’s circadian defense, it leaves a soft-matte finish for makeup and layers beautifully after Definitive Lifting Toner for enhanced antioxidant benefits.
