The Science

Dosed to perform.

Senn Blue is built on a simple principle: choose molecules with real evidence, dose them at meaningful concentrations, and protect the barrier so they can work.

The Hero Molecule

GHK-Cu, the copper tripeptide.

GHK-Cu is a small complex of three amino acids bound to a copper ion, naturally present in the body and understood to decline with age. In the literature it is associated with supporting the skin's renewal processes and the appearance of firmness and elasticity.

We dose it at a meaningful, efficacious concentration rather than a token amount, then support and stabilise it within a considered formula.

The Formula

Every ingredient earns its place.

GHK-Cu

Copper Tripeptide-1

A naturally occurring copper tripeptide and one of the most studied molecules in modern skin science. Dosed at 2% in the serum and 1% in the cream to support the look of firmness, smoothness and renewal.

Niacinamide

Vitamin B3

Helps refine the appearance of tone, pores and texture while supporting a comfortable, balanced complexion.

Ectoin

Extremolyte

A cell-protective molecule that helps defend against environmental stress and moisture loss for resilient-looking skin.

Ceramide Complex

Barrier Lipids

Reinforces the look of a healthy skin barrier, helping to lock in moisture and seal the regenerative serum beneath.

Beta-Glucan

Hydrating Polysaccharide

Delivers long-lasting hydration and a soothed, cushioned feel to the skin.

Multi-Peptides

Signal Peptides

A considered complex that supports smoother, firmer, more youthful-looking skin over time.

Four principles

Hydrate

Deep, lasting hydration that strengthens the look of the barrier.

Regenerate

Supports skin renewal and improves the look of resilience.

Restore

Calms and restores balance for a healthy, radiant complexion.

Protect

Antioxidant-rich protection against daily environmental stressors.

Experience the Protocol

Serum first, then cream. The complete regenerative ritual.
