Collection: Copper Peptides (GHK-Cu)

The most studied regenerative peptide in skincare. And the most underestimated.

GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a naturally occurring tripeptide that declines significantly with age — from approximately 200 ng/mL in plasma at age 20 to under 80 ng/mL by age 60. This decline correlates directly with the loss of skin repair capacity, collagen density, and regenerative function that defines visible aging.

What makes GHK-Cu extraordinary is the breadth of its mechanism. Research by Dr. Loren Pickart and subsequent studies have documented GHK-Cu's ability to modulate the expression of over 4,000 human genes — resetting aged tissue gene expression toward a younger, more regenerative state. No other topical active comes close to this scope of biological activity.

What GHK-Cu Does

Collagen & Elastin Synthesis — Upregulates collagen I, III, and elastin production for structural skin restoration.
Anti-inflammatory Signaling — Modulates TNF-α and IL-6, reducing chronic inflammation that drives accelerated aging.
Antioxidant Defense — Activates superoxide dismutase (SOD) and other endogenous antioxidant systems.
Wound Healing & Repair — Accelerates tissue remodeling and barrier restoration after damage or procedure.
Gene Expression Reset — Modulates 4,000+ genes toward a regenerative, anti-aging expression profile.

What's Inside

SerumScientist's GHK-Cu collection spans serums, ampoules, and high-concentration treatment formulas — from entry-level copper peptide serums to professional-grade ampoules for post-procedure and intensive repair protocols.

GHK-Cu modulates over 4,000 genes. Your copper peptide serum might not have enough of it. Ours does.
