GHK, a naturally occurring tripeptide composed of glycine, histidine, and lysine, was first identified in human plasma. It plays an essential role in skin and tissue repair. It functions by binding with copper ions, which enhances wound healing and skin regeneration. Research on GHK began with its discovery in plasma, where its concentration declines with age, sparking interest in its potential anti-aging properties. This peptide's ability to modulate gene expression and promote collagen production has made it a focal point in cosmetic research. Today, it is primarily studied for its effects on:
- Wound healing
- Skin regeneration
- Anti-aging effects
- Collagen production
It is also being studied for its potential to influence hair growth and improve skin elasticity.
