Palmitoyl Tripeptide-1 / Palmitoyl Tetrapeptide-7
Also known as: Signal Peptides · Copper Peptides · Matrixyl
Anti-agingBarrier repair
“Amino acid chains that signal skin to produce more collagen and elastin.”
What it does
Peptides are short chains of amino acids that act as biological messengers in the skin. Different types work differently: signal peptides (e.g., Matrixyl/palmitoyl peptides) stimulate collagen and elastin synthesis, carrier peptides (e.g., copper peptides) deliver trace elements that activate wound healing enzymes, and neurotransmitter-blocking peptides relax facial muscle contractions. They are a well-tolerated anti-ageing strategy with growing clinical evidence.

How to use
Apply as a serum or moisturiser morning and/or evening. Leave on the skin — do not rinse. Look for products with a stable, buffered pH.
Typical concentration: 1–10 ppm depending on peptide type
