Lines that were not there last year, skin that looks tired, hair that is thinning at the temples. Skin and hair ageing is one of the most searched concerns anywhere, and one copper peptide dominates the research: GHK-Cu. Here is what the studies show.

Why skin ages

As we age, collagen production falls, skin repair slows and the extracellular matrix breaks down. This is the biology behind lines, thinning and loss of firmness, and it is the target of skin-remodelling research.

What GHK-Cu is

GHK-Cu is a naturally occurring copper-binding peptide whose levels decline with age. Research led by Loren Pickart and others has associated it with collagen and elastin synthesis, skin remodelling, antioxidant activity and wound repair in cell and tissue studies (Pickart and Margolina, 2018 review). It has also been examined in the context of hair follicle signalling.

What the evidence supports

GHK-Cu has one of the more developed research bases among cosmetic peptides, spanning cell studies and topical applications, though study designs and quality vary. It is studied as a skin and tissue research compound rather than a guaranteed outcome.

The takeaway

Skin ageing is a matrix and repair problem, and GHK-Cu is the peptide most studied against it. Explore related research on tissue-repair peptides and cellular energy.
