GHK-Cu: what skin research can tell us

Understanding a copper peptide, what laboratory skin research has looked at and why the formulation matters.
By 24/sync Published Editorial review 2 min read

GHK-Cu is a copper-binding peptide complex with a long history in skin research. Know what the name means and what the studies looked at, and it is easy to see why it draws so much interest.

What does the name mean?

GHK refers to a short chain of three amino acids: glycine, histidine and lysine. Cu is the chemical symbol for copper. As a named peptide complex, it is more specific than a general reference to copper, so look for the full name on a label.

That specificity is useful when reading a product page. The exact name, the amount and the surrounding formulation tell you what you are getting.

Two words worth knowing

Skin research uses two terms you will meet often: topical and transdermal. Our guide to topical and transdermal delivery explains what each one means, in plain English.

What should you look for before buying?

Look for the full ingredient name, the amount and complete use instructions. A label that shows all three is a label you can read with confidence.

Know the format, too. Microneedles, injections and specially engineered carriers are different technologies. A 24/sync patch is simple by design: a clear patch, with the actives built into the adhesive layer that sits against your skin, designed to release steadily across the hours you wear it.

GHK-Cu at 24/sync

Glow pairs GHK-Cu with botanicals in one clear patch, made for skin that looks fresh and bright. Science & standards sets out the research behind each ingredient. Read it alongside the product details, then give it a couple of weeks of daily wear and notice how your skin looks and feels.

A clear standard

Our guides distinguish ingredient research from evidence for our finished patches. Read our evidence approach.

The product-specific question
