Buyer guide · GHK-Cu serums

Best copper peptide serum

Copper peptides (GHK-Cu) are the most-studied peptide in skincare — great for firmness, texture and renewal. Here are our top serum picks, what to look for, and how to use them.

What to look for

  • A named copper peptide — “GHK-Cu” or “copper tripeptide-1” — fairly high in the ingredient list.
  • A sensible concentration (many effective serums sit around 1%).
  • A simple formula without lots of strong acids in the same product.
  • Opaque or airless packaging (peptides and copper prefer stable, low-light storage).
  • Good reviews and, ideally, a brand that lists its actives clearly.

For the full science, see our GHK-Cu guide, and GHK-Cu vs Matrixyl if you’re choosing between peptide types.

How to use a copper peptide serum

Apply to clean skin, before heavier creams and oils; a pea-sized amount covers the face. Use it once or twice daily and give it 8–12 weeks. Keep it separate from strong vitamin C or acids in the same step (use one AM, one PM). Finish the morning with sunscreen. A faint blue-green tint is just the copper and rinses away.

Frequently asked questions

Look for a serum with a named copper peptide (GHK-Cu or copper tripeptide-1) fairly high in the ingredient list. Well-reviewed options include Asterwood Copper Peptides and The Ordinary Multi-Peptide + Copper Peptides 1%. The best one fits your budget and routine and is used consistently.
Because GHK-Cu works by supporting your own collagen and renewal, expect gradual change over about 8–12 weeks of daily use.
Many people separate them — copper peptides at one time of day, strong vitamin C at another — because high acidity can interfere. Copper peptide by day and a retinoid at night is a common, well-tolerated routine.
Topical copper peptides are regulated as cosmetics, sold over the counter, and very low-risk for most people. They can leave a faint blue-green tint that rinses away. Patch-test if your skin is sensitive.
