How we scored it
Assembled from asparagine, glycine and proline (fermentation/hydrolysate amino acids); coupling reagents leave no mass.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Synthesised by coupling the natural amino acids asparagine, glycine and proline. Synthesis reagents contribute no mass to the final peptide.
In plain English
A lab-assembled chain of three amino acids (asparagine, glycine, proline) used in skincare to condition and support skin.
CosIng definition: Tripeptide-13 is a synthetic peptide consisting of asparagine, glycine and proline; Asparagine, synthetic tripeptide with glycine and proline
