| Study Type | Narrative Review |
| Evidence Level | V |
| Sample | Review of preclinical and clinical wound/skin data |
| Peptide(s) Studied | GHK-Cu |
Key Findings
- GHK-Cu acts as chemoattractant for macrophages, mast cells, and capillary endothelial cells
- Increases collagen, elastin, and metalloproteinase synthesis
- Anti-inflammatory: blocks oxidative damage to tissue
- Stimulates fibroblast and keratinocyte proliferation
- Clinical skin studies show tightening, wrinkle reduction, and improved clarity in aged skin
- Effective in wound healing, bone repair, and intestinal tissue remodeling
Study Design
Comprehensive narrative review covering GHK-Cu's mechanisms in tissue remodeling across multiple tissue types. Includes references to human skin clinical observations.
Limitations
- Human skin data largely from cosmetic product studies, not rigorous RCTs
- Single-author review (Pickart is the patent holder for GHK-Cu applications)
- Conflict of interest: Pickart has commercial interests in GHK-Cu
Clinical Relevance
Foundational clinical applications paper. The human skin data, while from cosmetic studies, provides some of the only clinical evidence for GHK-Cu effects. Relevant for skin rejuvenation protocols and the GLOW/KLOW blend product rationale.
