SKIN · 12 WEEKS · LOT #PK-2611

Clear.

Skin clarity, repair, and tone — from the inside out.

A 12-week dermal renewal arc built around GHK-Cu, a copper-binding tripeptide naturally found in human plasma. Clear targets collagen synthesis, dermal density, and barrier integrity for visible improvements in skin tone, fine lines, and post-inflammatory pigmentation.

· THE COMPOUND

What's in the vial.

01
GHK-Cu
Copper-binding tripeptide
DESCRIPTION

Glycyl-L-histidyl-L-lysine bound to copper(II). Naturally present in plasma, saliva, and urine, with concentrations declining sharply after age 30.

MECHANISM

Modulates over 4,000 human genes, upregulating collagen, decorin, and elastin synthesis while downregulating inflammatory cytokines. Stimulates fibroblast activity and supports antioxidant defense via SOD induction.
