Short answer
What are copper peptides?
Copper peptides are small peptides, short chains of amino acids, paired with copper. In skincare you will find them in leave-on products like serums. The one people talk about most is GHK-Cu, which is why "copper peptides" and "GHK-Cu" often get used interchangeably. Our guide on what GHK is breaks down the underlying peptide in more detail.
GHK, GHK-Cu & Copper Tripeptide-1
The most confusing part for newcomers is that one ingredient has several names. Here is the short version:
- GHK: the peptide itself (three amino acids).
- GHK-Cu: GHK bound to copper, the form used in most products.
- Copper Tripeptide-1: the ingredient-label name for GHK-Cu.
For a fuller explanation, see what GHK-Cu means.
What people use them for
In cosmetic use, copper peptides come up around the appearance of skin: texture appearance, firmness appearance, and visible signs of aging. We stick to appearance-focused language instead of promising specific outcomes. Our guide to copper peptides for skin covers who usually likes them and who should be cautious.
Fitting them into a routine
A copper peptide serum is usually applied after cleansing and before heavier moisturizers. Daytime routines should always finish with sunscreen. If you want a step-by-step layout, including a minimal beginner routine and a sensitive-skin version, read the copper peptide serum routine guide.
Shopping without the hype
When you are reading a label, look for Copper Tripeptide-1, and check whether the formula is simple and fragrance-free. It also helps to know how copper peptides differ from other actives you might already use. Our copper peptides vs retinol comparison lays out the trade-offs in plain terms, without hype.
