Does GHK-Cu (inj/oral) actually work on skin?
This is a different question from whether it works injected, and the answer is often different too — a molecule has to survive the stratum corneum before any of its biology matters. Full GHK-Cu (inj/oral) breakdown →
Human clinical evidence
- The best-evidenced peptide in this section for topical use, and unusually it is evidenced as a topical specifically rather than borrowed from injection studies. Controlled work reports increased collagen and elastin, improved skin firmness and reduced fine lines over 12 weeks in facial creams, and improved wound closure in dermatology settings.
Correlative data
- Decades of use in cosmetic dermatology, and one of very few peptides that survived from prescription wound care into ordinary skincare on the strength of results rather than marketing.
- Scalp use for density is widespread and reported experience is positive but slow — months, not weeks — and far less dramatic than minoxidil.
How the mechanism reads
- A copper-binding tripeptide (glycyl-L-histidyl-L-lysine) at about 340 Da — small enough to actually cross the stratum corneum, which is why it works topically when larger peptides do not. It upregulates collagen I, III and IV and elastin, signals metalloproteinase remodelling, and delivers copper as a cofactor for lysyl oxidase, the enzyme that cross-links collagen.
- The copper is the caveat. It is what makes it work and also what makes it stain, oxidise and interact badly with direct vitamin C in the same layer. Separate them by routine, AM and PM.
How to use GHK-Cu Hair Density Conditioner
Step 8 — Hair & scalp
After shampoo, mid-length to ends; scalp if it does not weigh you down. Keep it out of the same layer as direct vitamin C — copper and ascorbic acid deactivate each other. Vitamin C in the morning, copper peptides at night, and both keep working.
What to expect, and when
Condition immediately; density is a 4–6 month question.
What not to layer with GHK-Cu Hair Density Conditioner
- GHK-Cu (inj/oral) + Vitamin C — Copper peptides and direct (L-ascorbic) vitamin C deactivate each other. Not dangerous — just wasteful. Split them: vitamin C in the morning, copper peptide at night.
