Pal-AHK is a synthetic peptide, combining alanine, histidine, and lysine with a palmitoyl group, that functions by promoting collagen production and stimulating skin repair. Interest in Pal-AHK started around the early 2000s, focusing on its potential to enhance skin elasticity and reduce the appearance of wrinkles. This peptide is distinctive in its ability to penetrate the skin barrier effectively, thanks to the palmitoyl group, which improves its lipid solubility. Beyond that, work continues on exploring its comprehensive role in skin health. Today, it is primarily studied for its effects on:
- Anti-aging applications
- Skin elasticity enhancement
- Collagen synthesis
- Wrinkle reduction
- Skin barrier penetration
