What it is
A peptide with four amino-acid units and an attached fatty-acid part. The added part distinguishes its ingredient name.
Why it is used
Croda includes it in Matrixyl 3000, an ingredient blend marketed for wrinkle appearance. This does not confirm a branded blend or its dose in this serum.
What the evidence means
The supplier describes a blend, not an independent test of this ingredient alone in The Ordinary serum.
Precautions and possible reactions
A safety review addresses reported cosmetic uses, not every possible formula or individual reaction.
Cosmetics can cause irritation or allergic reactions. Check the full ingredient list and follow product directions.
What this means for your comparison
A peptide blend’s claims cannot be assigned to this ingredient alone or used to rank these two serums.
