What Is Oligopeptide-79?
Oligopeptide-79 is a short-chain peptide — a molecule composed of amino acids linked together. Peptides are naturally occurring in skin and hair, where they play structural and functional roles. In cosmetic formulations, Oligopeptide-79 is used as a conditioning agent, meaning it helps to coat and smooth the hair fibre surface, improving texture and manageability.
This ingredient appears more commonly in haircare products than skincare, reflecting its primary functional role in conditioning rather than treating skin directly.
How It Works
Oligopeptide-79 works by adhering to the outer layer of the hair shaft, the cuticle. This coating effect smooths the surface, which reduces light scattering and creates a glossier appearance. The conditioning film also helps to seal moisture within the hair and protect against environmental damage and mechanical stress from brushing or heat styling.
Clinical Evidence & References
The evidence base for Oligopeptide-79 specifically is limited in published literature. Most data comes from ingredient suppliers and formulators rather than independent clinical trials. The ingredient is typically used in concentrations designed to condition hair rather than deliver therapeutic skin benefits.
Peptides more broadly have been studied for skin health, particularly in relation to collagen support and barrier function, but the specific mechanism and efficacy of this particular oligopeptide for skin concerns remains unclear.
How to Use
This ingredient is most effective in rinse-off haircare products (conditioners, masks) or leave-in formulations applied to damp hair. For skincare products containing this peptide, follow the product instructions — typically once or twice daily depending on the formulation type and your individual needs.
