Palmitoyl Tripeptide-1, also known as Pal-GHK, is a synthetic peptide used primarily in cosmetics. It functions by stimulating collagen production through interaction with fibroblast growth factors in the skin. Early work on Palmitoyl Tripeptide-1 focused on its potential to enhance skin elasticity and reduce signs of aging. This peptide has been studied in the context of the extracellular matrix and its role in wound healing and skin regeneration. Today, it is primarily studied for its effects on:
- Skin elasticity enhancement
- Collagen production
- Anti-aging effects
- Wound healing
Researchers are also looking at its impact on skin barrier function.
