Definitive Line Serum

Most serums ask for weeks of patience before showing results. Definitive Line Serum 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.

Dual-Action Performance

On Application — Instant smoothing and tightening of horizontal and lateral surface lines

Over Time — Sustained collagen production and enduring skin smoothness

The Formulation

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 neutralise oxidative damage at the surface.

Key Actives

SYN®-AKE Peptide — The industry benchmark for topical collagen production and skin tightening. Mimics the smoothing and lifting effects of cosmetic-surgical procedures through topical application. Delivers visible line reduction on contact and builds structural improvement over time.

Cyclopeptide-5 — Works in concert with SYN®-AKE to tighten and smooth both horizontal and lateral surface lines instantly. Amplifies the immediate visible effect of the peptide complex.

Multi-Molecular Hyaluronic Acid Complex — A unique blend of Hyaluronic Acids at varying molecular weights ensures hydration is delivered at every depth of the skin. Surface plumping is immediate; deep structural hydration builds with continued use.

Vitamin E and Resveratrol — A dual antioxidant defence that neutralises free radical damage and reduces visible signs of environmental stress. Protects collagen already present from oxidative breakdown.

Texture and Experience

A uniquely generous serum texture that delivers a high concentration of actives in every application. Skin feels smoother, more taut, and noticeably more rested from first use. Enduring smoothness builds with consistent application.
