GHK-Cu is a copper-binding peptide with regenerative properties. It works by facilitating wound healing and tissue repair through its role in collagen synthesis and cell signaling pathways. Early work on GHK-Cu focused on its ability to enhance skin and hair health. Studies have shown its involvement in reducing oxidative stress within the extracellular matrix. Today, it is primarily studied for its effects on:
- Improving skin elasticity
- Wound healing
- Hair growth enhancement
Researchers are also looking at its potential impact on anti-aging treatments.
