Tripeptide-10 (Decorinyl)
INCI name · tripeptide-10
In short
Tripeptide‑10, known as Decorinyl, supports the organisation of collagen fibres so they form a more regular and stable network. This helps improve skin smoothness and elasticity over time.
What it is
Commercially Decorinyl (Lucas Meyer Cosmetics); stimulates decorin production in dermal fibroblasts; decorin is a small leucine-rich proteoglycan that acts as a collagen fibril diameter regulator and spacer, controlling inter-fibril distance and mechanical integrity; addresses age-related collagen disorganisation (loss of fibrillar regularity) rather than just collagen quantity; best combined with collagen-stimulating peptides for synergistic ECM quality improvement.
