OUR INGREDIENTS
GHK-Cu
The regenerative copper signal
Regenerates
Stimulates collagen, elastin, and glycosaminoglycan production.
Repairs
Documented anti-inflammatory and healing properties.
Restores
Rebuilds tissue integrity at a cellular level.
What it is
A naturally occurring tripeptide bound to a copper ion, first identified in human blood plasma in 1973 — one of the body’s own signaling molecules for tissue repair.
How it works
GHK-Cu stimulates fibroblasts to produce collagen, elastin, and glycosaminoglycans (the building blocks of firm, resilient skin). It also has documented anti-inflammatory and antioxidant properties that support overall skin recovery.

Why we chose it
For our most restorative product, we wanted an ingredient with a genuine biological mechanism — not just a trendy buzzword. GHK-Cu’s decades of peer-reviewed research made it the clear anchor for The Serum CU.
