Oligopeptide-2 is a synthetic peptide consisting of amino acids lysine, serine, and threonine. It is known for its ability to act on dermal fibroblasts, promoting the synthesis of macromolecules such as collagen types I, III, and IV, fibronectin, and glycosaminoglycans. This peptide works to repair and rebuild the extracellular matrix and the dermal-epidermal junction (DEJ), addressing wrinkles and improving skin appearance from the deeper layers of the skin. Furthermore, Oligopeptide-2 has been shown in experimental studies to effectively prevent and reduce the appearance of wrinkles, making the skin look younger and more elastic. In cosmetic applications, Oligopeptide-2 is widely used in anti-aging skincare products, wound healing, and sometimes in medical products, particularly where accelerated skin or tissue repair is needed.
