Palmitoyl Tripeptide-1

INCI Palmitoyl Tripeptide-1

Signal Peptide Active Active Ingredients

What it is & what it does

Palmitoyl Tripeptide-1 is a lipid-modified signal peptide used in anti-aging formulas to support extracellular-matrix and collagen-related signaling.
Clinical evidence often comes from multi-peptide complexes rather than the ingredient isolated by itself. A 12-week eye-cream study containing Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 reported improvements in hydration, elasticity and collagen density, so it deserves peptide-active status while keeping the evidence context clear.

Usage & cautions

Generally well tolerated in cosmetic formulas.
Information approach Consumer-friendly summaries are informed by established cosmetic ingredient references such as INCIDecoder and Paula’s Choice Ingredient Dictionary, while avoiding turning ingredient-level evidence into medical claims about the finished product.
