What are peptides?
A large group of compounds made up of short chains of amino acids. On the ingredient list, you can find the name Palmitoyl Pentapeptide-4 and others. The dictionary uses both the common name and the INCI name, so you can compare the explanation with the packaging.
What do peptides do for skin and the product?
Different peptides are used for different skincare purposes.
Active ingredients are used for a specific skincare purpose. Amount, stability and combination with other ingredients determine what a product can do. An ingredient name alone does not substantiate a particular result.
Peptides are not one ingredient. Evidence for one peptide does not automatically apply to all others.
How to read the ingredient list
Look at the product's purpose and overall composition. Position on the list does not tell you the exact concentration used or how your skin will react. One substance can serve several purposes in the same product.
