Description

Tripeptide-29 is the synthetic peptide consisting of glycine, proline and hydroxyproline

Purpose

Function

Collagen-mimetic biomimetic peptide that replicates the Gly-Pro-Hyp (glycine-proline-hydroxyproline) tripeptide sequence — the fundamental repeating unit of the collagen triple helix. Provides direct structural reinforcement and stimulates collagen synthesis by presenting a native ECM sequence to fibroblasts. Mechanism differs from signal peptides: Tripeptide-29 mimics the structural building block rather than a matrikine fragment.

Verdict

Tripeptide-29 is a collagen-mimetic peptide presenting the native Gly-Pro-Hyp collagen repeat directly to skin cells for structural reinforcement without regulatory restrictions in EU or US, though clinical substantiation remains limited.

US Note

No specific FDA restrictions. No pre-market approval required under MoCRA for cosmetic peptides.
