GHK-CU
GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper-binding tripeptide that has become one of the most extensively studied peptides for skin repair, wound healing, collagen production, and hair health. Unlike peptides that primarily affect hormones, GHK-Cu acts as a signaling molecule involved in tissue remodeling and repair.
Potential benefits studied
Research has investigated GHK-Cu for:
- Skin rejuvenation: May stimulate collagen and elastin production, improve skin elasticity, reduce the appearance of fine lines, and support wound healing.
- Hair health: May support hair follicle function and has been studied as a potential treatment for certain types of hair loss.
- Tissue repair: May promote healing of skin and soft tissues through effects on fibroblasts and the extracellular matrix.
- Anti-inflammatory and antioxidant effects: May help reduce inflammation and oxidative stress in laboratory and animal models.
How it works
GHK-Cu appears to:
- Bind copper ions and deliver them where they're needed for tissue repair.
- Stimulate fibroblasts to produce collagen, elastin, and glycosaminoglycans.
- Influence gene expression involved in tissue remodeling and wound healing.
- Support angiogenesis (formation of new blood vessels) during healing.
Forms available
GHK-Cu is commonly found as:
- Topical serums and creams, where there is the strongest clinical evidence for skin-related uses.
- Injectable formulations, which are used in some research and wellness settings but have much less human clinical evidence than topical products.
Side effects
Topical GHK-Cu is generally well tolerated. Possible side effects include:
- Mild skin irritation
- Redness
- Itching
Safety data for injectable GHK-Cu are much more limited, and its long-term effects have not been well established in controlled human studies.
Evidence
Among peptides marketed for cosmetic purposes, GHK-Cu has one of the stronger evidence bases for topical skin applications, including studies on collagen production, wound healing, and skin appearance. Evidence for injectable use or broader systemic anti-aging effects remains limited and investigational.
