Peptides are short chains of amino acids (the building blocks of proteins). They act as highly targeted biological messengers in your body, regulating everything from immune responses and hormone production to muscle growth. In medicine and skincare, they are used to trigger specific healing or anti-aging processes. How They Work Peptides act like biological keys. When they bind to specific receptors in your cells, they send commands that tell the body to perform a specific task, such as: Signaling collagen production (in skincare) Regulating metabolism (like GLP-1 weight management drugs) Accelerating tissue repair (such as investigational healing peptides).
