What Is Palmitoyl Oligopeptide?

Palmitoyl Oligopeptide is a well-established peptide that signals fibroblasts to increase collagen production. As one of the earlier peptides adopted in cosmetic formulations, it has a substantial track record of use and research supporting its anti-ageing benefits.

The oligopeptide stimulates cell communication, encouraging the skin to behave as it did when younger. The palmitoyl group ensures effective delivery through the lipid-rich skin barrier.
