Understanding peptides in skincare.
Peptides are short chains of amino acids. Their sequence and structure help define their properties. Explore how peptide identity, multi-peptide complexes and the complete skincare formula shape the context behind ingredient claims.
Amino acid chains
The number and sequence of amino acids help define each peptide’s structure and properties. Different peptides are not interchangeable.
Multi-Polypeptide complexes
A multi-polypeptide complex combines different polypeptide chains in one blend. Their identity, concentration and formulation help determine the properties of the finished skincare product.
The complete formula
Concentration, stability and delivery matter. Findings about an individual peptide should be considered alongside evidence for the finished skincare product.
Peptides in skincare: your questions.
Peptides are chains of amino acids used as ingredients in skincare formulations. Their properties depend on their specific structure, while a product’s performance depends on the complete formula. Evidence for one peptide does not automatically apply to every peptide serum or cream.
A multi-polypeptide complex is a blend of different polypeptide chains, each made from linked amino acids. Its properties depend on the specific polypeptides, their concentrations and the complete formulation. The term alone does not establish a skincare product’s effectiveness.
