Palmitoyl Tetrapeptide-7

Overview
Palmitoyl Tetrapeptide-7 is a synthetic signal peptide widely used in cosmetics and skincare products. It consists of a sequence of four amino acids (a tetrapeptide) attached to a palmitic acid group (palmitoyl), which enhances its ability to penetrate the skin barrier. Its primary function is to target and reduce inflammatory responses and alleviate under-eye puffiness, making it renowned as a star ingredient for its "anti-inflammatory and anti-puffiness" properties.
