GHK-Cu

Also known as Copper Peptide

A naturally occurring copper-binding tripeptide celebrated in skincare research for collagen, wound healing and hair-follicle support.

What it is

GHK-Cu is a small tripeptide that naturally binds copper. Levels in the body decline with age, which is part of why it's so heavily studied for skin and tissue quality. It's one of the best-known "copper peptides" in cosmetics.

How it's thought to work

The GHK-copper complex is thought to signal tissue remodelling and repair: stimulating collagen and elastin production, supporting antioxidant defences, and promoting healthy blood-vessel and hair-follicle activity.

Potential health benefits

Researched for:

  • Firmer, smoother skin and reduced signs of ageing.
  • Wound healing and tissue repair.
  • Hair-follicle support and thickness.

What the research says

GHK-Cu has a substantial body of in-vitro and topical research behind its skin-remodelling effects, and it's a common active in cosmetic formulations. Topical evidence is the strongest part of its profile.

Considerations

A research compound. Topical use is common in cosmetics; other uses are exploratory. Seek professional advice as appropriate.
