Ingredient reference
Peptides
A peptide is a short chain of amino acids. On a label it appears under a specific name — ours records Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7 — and that exact name tells you more than the category word on the front of the box.
What the word covers
Peptide is a category, not an ingredient. Amino acids are the units proteins are built from; link a few together and you have a peptide. Hundreds are used in cosmetics, they are not interchangeable, and two products both described as containing peptides can contain entirely different molecules. That is why the ingredient list is the only reliable place to look.
The names in our formulas
Our catalogue records Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7. Both are palmitoylated — a fatty-acid chain is attached, which helps the peptide blend into a formula that contains oils. They appear under those full names, usually low in the list, which is normal for ingredients used at small percentages.
How to read a peptide on a label
Front-of-pack peptide language tells you nothing about which peptide or how much. Turn the box over. If the specific name is there, you know what you are buying. We publish the complete formula on every product page for that reason.
What this page does not do
This is an ingredient reference. It describes what the ingredient is, how it behaves in a formula, and where it appears in our catalogue. It does not make a performance, safety, suitability or timeline claim, and it does not replace the complete ingredient list on a product page.
Quick answers
Is peptide one single ingredient?
No. It is a category name covering many different molecules. The complete ingredient list gives the specific name.
Are two products that both contain peptides the same?
Not necessarily. They can contain entirely different peptides. Compare the complete ingredient lists rather than the front labels.
Why do peptides sit near the end of an ingredient list?
Cosmetic ingredients are listed in descending order of concentration down to one percent, after which the order is at the formulator's discretion. Ingredients used at small percentages sit low in the list.
Where do I find the complete formula?
On the product page for the item you are considering. Read the complete ingredient list there before purchasing.
