Research information only · not approved for use. GHK-Cu appears in many topical cosmetic products. Injectable GHK-Cu is not FDA-approved, and the FDA has raised safety concerns about its use in compounding. Educational information only — quote requests are disabled.
✱ Overview
What is GHK-Cu?
GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) bound to a copper ion. It is found in human plasma, and its levels decline with age.
Most research concerns topical application in skin care and wound models. Topical cosmetic findings should not be extrapolated to injectable use.
✱ Mechanism
How it works
In laboratory studies, GHK-Cu stimulates fibroblasts to produce collagen, elastin and glycosaminoglycans — key components of the extracellular matrix that gives skin its structure.
It also appears to modulate enzymes that break down and rebuild matrix proteins, and delivers copper, a cofactor for lysyl oxidase, which cross-links collagen.
✱ Key research areas
What the science says — and how sure it is.
01
Collagen & elastin biology
Preliminary findings
Cell studies consistently show increased collagen and elastin synthesis by fibroblasts.
02
Topical skin remodeling
Preliminary findings
Small cosmetic trials of topical creams report improvements in fine lines and firmness.
03
Extracellular matrix & wound repair
Preliminary findings
Animal wound models show faster healing and matrix remodeling.
04
Hair follicle research
Experimental hypothesis
Limited lab data on follicle size; no reliable clinical evidence for regrowth.
05
Injectable use
Experimental hypothesis
Not established and not approved for skin rejuvenation or hair growth.
