GHK-Cu: evidence from topical skin studies
Fibroblast cultures, ex-vivo skin and studies in people provide different levels of direct evidence for a cosmetic claim.

Why formulation and application route matter
The penetration experiment measured copper in isolated skin and collected fluid, not clinical benefit in living participants.

Before you read
What does GHK-Cu mean?+
GHK names the tripeptide glycine-histidine-lysine; Cu indicates its copper complex. A chemical identity and a clinical claim are separate statements.
Can topical evidence be applied to injectable products?+
No automatic transfer is justified. Route changes exposure and the questions that need testing. A topical or laboratory study does not establish injectable safety or benefit.
