Copper Peptide (GHK-Cu) Serum & Skincare

Copper peptides, listed on labels as copper tripeptide-1 (GHK-Cu), are one of the most-researched cosmetic peptides. Our copper peptide range pairs GHK-Cu with ectoin, panthenol and hyaluronate for smooth, hydrated-looking skin.

Products

• Copper + Ectoin Peptide Serum (30 mL): A lightweight daily serum for a smooth, hydrated-looking finish. Key ingredients: Copper tripeptide-1, Ectoin, Panthenol.
• Copper Peptide Hydration Sheet Mask (5 masks): A hydrating mask for smoother, refreshed-looking skin. Key ingredients: Copper tripeptide-1, Glycerin, Hyaluronate.

How to choose

• For daily use, choose a leave-on serum: it gives the peptide the most contact time.
• Copper peptide formulas can have a blue tint from the copper. That's normal.
• As a precaution, use copper peptides at a different time of day from pure L-ascorbic acid (vitamin C) or strong acids.
• Sheet masks are a once- or twice-weekly hydration boost, not a replacement for a daily serum.

Is copper tripeptide-1 the same as GHK-Cu?

Yes. Copper tripeptide-1 is the ingredient-list (INCI) name for GHK-Cu, a peptide naturally found in human plasma that is bound to copper.

Can I use a copper peptide serum with vitamin C?

Yes, but a common precaution is to use them at different times of day, for example vitamin C in the morning and copper peptides at night, because pure vitamin C needs a very low pH while copper peptides prefer a milder pH.

How long do copper peptides take to work?

Give a copper peptide serum 8–12 weeks of consistent daily use. Hydration benefits from the surrounding formula are felt sooner.
