GHK-Cu (Copper Peptide) and Skin Regeneration
The naturally occurring copper-binding tripeptide GHK has been studied for its effects on extracellular matrix remodeling, antioxidant defense, and skin appearance.
GHK is a tripeptide (glycyl-L-histidyl-L-lysine) that forms a complex with copper(II) ions. Published reviews describe roles in collagen and elastin synthesis, antioxidant gene expression, and modulation of inflammatory pathways relevant to skin biology.
Topical formulations have been studied in small human trials for fine lines, photodamage, and wound healing support. Effect sizes vary, and product quality and formulation matter significantly.
Key takeaways
- GHK-Cu interacts with extracellular matrix remodeling pathways.
- Most cosmetic evidence comes from small, short-term studies.
- Formulation and stability strongly affect outcomes.
