Peptide
What Peptide is & what it does
Peptide is a general term for short chains of amino acids, the building blocks of proteins, used widely in skincare. Depending on the specific peptide, formulators include them as conditioning or signaling agents intended to support the look of firmness, smoothness and hydration. Because "Peptide" is a broad label rather than a single molecule, the exact role depends on the particular peptide used. Peptides are generally well tolerated in cosmetic use.
