GHK-Cu

What it is

GHK-Cu combines a three-amino-acid peptide with copper. Researchers first found the peptide in human blood plasma.

A sizeable body of published laboratory research examined it in skin science.

How researchers think it works

Cell studies suggested that GHK-Cu carried copper and changed the activity of genes involved in skin structure, including collagen-related genes.

Studies of cultured cells reported changes across many genes after exposure to GHK-Cu.

What has research seen in people?

Most of the work is laboratory skin-cell research, which reported changes in the activity of genes linked to collagen and skin structure.

A handful of small human skin studies reported measured changes in skin appearance, but they had few participants and often no blinding or independent funding.

So the honest summary is: interesting cell evidence, thin human evidence.

What studies have found

• Most published research used fibroblasts and keratinocytes, two types of skin cell grown in laboratories.
• A few small skin and cosmetic studies reported changes in skin measurements. These studies generally included few participants.

What we still do not know

• Many cosmetic studies did not clearly use blinded testing, comparison products or independent funding.
• Changes seen in cells did not prove a health effect in people.
