Palmitoyl Tripeptide‑5 – The Signal Peptide That Rebuilds Collagen for Youthful, Resilient Skin
A biomimetic tripeptide that stimulates collagen I, III, and IV, restores skin density, reduces wrinkles, and improves elasticity. Clinically proven in 8 weeks. Safe, non‑irritating, and trusted by leading brands.
Product Overview:
Palmitoyl Tripeptide‑5 is a synthetic peptide composed of the amino acid sequence Gly‑Pro‑Hyp (glycine‑proline‑hydroxyproline), a key fragment of type I collagen. It belongs to the signal peptide class – capable of penetrating the stratum corneum and reaching the dermis, where it communicates with fibroblasts to boost the production of collagen (types I, III, and IV) and glycosaminoglycans (GAGs). Unlike simple moisturisers, this active addresses the root cause of aging by restoring the extracellular matrix.
| Benefit | Mechanism / Data |
|---|---|
| 🧬 Stimulates collagen synthesis | Increases collagen I, III, and IV production in human fibroblasts – rebuilding the dermal matrix. |
| ✨ Reduces wrinkles & improves elasticity | 8‑week clinical study (n=15, average age 44.1, twice daily): significant improvement in wrinkles, skin elasticity, density, and thickness. |
| 📉 Decreases subepidermal low‑echogenicity band (Sb) | Sb is a skin age index; after 56 days, Sb was significantly reduced – indicating younger, tighter skin structure. |
| 👁️ Visibly reduces eye wrinkles | Before/after photos showed marked reduction in periorbital fine lines and depth after 56 days. |
| 🌿 Safe & well‑tolerated | Non‑irritating, no adverse reactions; used in premium global brands (Lancôme, Estée Lauder, etc.). |

Proven Efficacy (8‑week clinical study, n=15, mean age 44.1):
-
Wrinkles, elasticity, density, thickness: all significantly improved (p<0.05) at days 28 and 56.
-
Subepidermal low‑echogenicity band (Sb): a marker of skin aging – decreased markedly after 56 days, indicating younger dermal structure.
-
Visual assessment: eye wrinkles visibly reduced and shallower (photographic evidence).
