Small chains of amino acids called peptides play an essential role in many body functions. Studies have recently examined the health and wellness benefits of these versatile molecules. From skincare to muscle growth, peptides are studied and used in numerous applications. Signal peptides Signal peptides are like messengers in the body. They work by telling cells to perform specific actions. For example, signal peptides can instruct skin cells to produce more collagen in skincare. This can lead to firmer, more youthful-looking skin. Some standard signal peptides include: Palmitoyl Pentapeptide-4: Encourages collagen production Acetyl Hexapeptide-8: May help relax facial muscles, reducing wrinkles Carrier peptides These peptides act like delivery trucks in the body. They transp
