What Is Palmitoyl Proline?

Palmitoyl Proline is an amino acid derivative that combines proline, a key component of collagen, with palmitic acid for enhanced skin penetration. It supports the skin's collagen production and maintenance.

This ingredient helps improve skin firmness and elasticity by providing building blocks for collagen synthesis while the lipid modification ensures effective delivery to target cells.
