Ingredient guide

What it is and what it does

About this ingredient: EU CosIng ingredient registry (via Open Beauty Facts taxonomy) ↗

Peptide
An ingredient made from linked amino-acid units. The peptide name identifies a particular material, not a shared clinical effect for all peptides.

Function definitions: European Commission: Cosmetic peptide nomenclature ↗

Registry functions describe possible formulation roles, not results for a finished product. A dictionary entry is not an approval or a safety assessment.

A closer look

What the research shows

Laboratory and human research

The complete cream improved measured periorbital hydration, elasticity and ultrasound collagen density over 12 weeks.

What this does not tell us

The peptide was combined with other actives, preventing independent attribution. The article gives internally inconsistent descriptions of control and blinding, so the clinical design remains uncertain.
