The Science

Why copper
peptides work.

GHK-Cu is a tripeptide that occurs naturally in human plasma, saliva, and urine. In youth, concentrations are high — skin repairs itself effortlessly. By age 60, levels have dropped by 60%. The science is clear: replenishing GHK-Cu signals the skin to rebuild.

Get the Serum
Collagen + Elastin
Activates fibroblasts to produce collagen and elastin — the structural proteins responsible for firm, youthful skin.
Cellular Renewal
Accelerates skin cell turnover and tissue repair, fading scars, hyperpigmentation, and sun damage over time.
Antioxidant Defence
Neutralises free radicals and reduces oxidative stress — the primary driver of premature aging and skin degradation.
Deep Hydration
Stimulates glycosaminoglycan production, binding and retaining moisture deep within the dermis for lasting plumpness.

Four steps.
Transformed skin.

3–5 drops into your palm. Warm between fingertips to activate the peptide complex.
03
Press In
Press — don't rub — into face, neck, and décolletage. Hold to allow full absorption.
04
Seal
Follow with moisturiser to lock in the copper peptides and support your skin barrier.
