What Is Palmitoyl Tripeptide-5?

Palmitoyl Tripeptide-5 is a synthetic peptide that mimics the action of Transforming Growth Factor Beta (TGF-β), a natural protein that stimulates collagen production. It activates latent TGF-β and triggers the production of new collagen in the skin.

This peptide offers a targeted approach to boosting the skin's collagen-building machinery. By mimicking natural growth factors, it provides anti-ageing benefits without the complexity of delivering actual growth factors to the skin.
