In plain English
Matrixyl is a trade name for a group of lab-made peptides, such as palmitoyl pentapeptide-4 and palmitoyl tripeptide-1. Skincare brands add them to serums and creams for a smoother, firmer look. They're cosmetic ingredients, not medicines, so the label claims are about how skin looks and feels. Some brands state a percentage and some don't. If a product doesn't say how much it contains, compare it with others that do.
