Peptide therapy uses short chains of amino acids, the body's own signaling molecules, to support specific functions like tissue repair, energy, or skin health, depending on the peptide used. It has become an increasingly popular part of longevity and wellness planning, offering a more targeted approach than broad supplementation.
What Are Peptides? How They Work
Peptides are short chains of amino acids that act as messengers in the body, signaling cells to carry out specific functions such as producing collagen or supporting tissue repair. Because they're built from the same amino acid building blocks the body already uses, peptides are able to interact with existing cellular signaling pathways rather than introducing an entirely foreign mechanism.
Cleveland Clinic explains that peptides used in skin care may help boost the production of collagen and elastin, though the strength of evidence varies by specific peptide and formulation, and outcomes can differ significantly depending on which peptide is used and how it's administered.
