What it is
Pentapeptide-13 is a short chain of five amino acids produced by peptide synthesis for use in cosmetic formulations. Like other cosmetic peptides it is included as a skin-conditioning agent intended to support the appearance of smooth, well-maintained skin. It is typically used at low concentrations within the water phase of serums and creams.

Short synthetic peptides are generally well tolerated and are not recognized fragrance allergens or comedogenic. They are used at low levels, and irritation is uncommon, though individual sensitivity is always possible.
Origin & sourcing
