A Multi-Pathway System

Our formula is designed as a layered peptide system—each component targeting a different aspect of skin behaviour to deliver a refined, cumulative result.

Skin Quality Pathway

Copper Tripeptide-1 (GHK-Cu)

Function: Supports overall skin condition and renewal

Copper peptides are widely recognised for their role in maintaining healthy-looking skin. Within this formula, GHK-Cu helps improve the appearance of tone, texture, and overall skin vitality.

What this means on skin:

  • More even-looking tone
  • Improved texture and clarity
  • Healthier, more resilient appearance

Barrier & Hydration System

Ectoin + Panthenol + Multi-Humectant Complex

Function: Protects, hydrates, and maintains balance

This supporting system ensures the skin remains hydrated and refreshed while peptides perform. Ectoin helps defend against environmental stress, while panthenol and amino acid hydrators maintain moisture balance.

What this means on skin:

  • Deep, lasting hydration
  • Reduced dryness and sensitivity
  • A stronger, more stable skin barrier

Expression Line Pathway

Acetyl Hexapeptide-8 + Heptapeptide-8 (Argireline)

Function: Targets the appearance of dynamic wrinkles

These peptides are selected for their ability to help reduce the look of expression lines caused by repeated facial movement. By supporting a softer, more relaxed appearance, they contribute to visibly smoother skin over time.

What this means on skin:

  • Softer-looking forehead lines
  • Reduced appearance of crow’s feet
  • A more refined, less tense surface

 Structural Support Pathway

Palmitoyl Tripeptide-1 + Palmitoyl Tetrapeptide-7 (Matrixyl™)

Function: Supports firmness and skin structure

This combination of signal peptides works to support the skin’s natural structural components, improving the appearance of elasticity and reducing the look of fine lines.

What this means on skin:

  • Improved firmness over time
  • Smoother skin texture
  • Reduced visible wrinkle depth

How It Works Together

Rather than relying on a single active, this formula works across multiple pathways:

  • Expression lines are softened
  • Skin structure is supported
  • Overall skin quality is improved
  • Barrier integrity is maintained

The result is skin that appears smoother, firmer, and more balanced—without disruption.
