How we scored it
Oligopeptide-1 is the tripeptide glycyl-histidyl-lysine (GHK) C14H24N6O4 340.4 Da built from fermentation amino acids; peptides assembled from amino acids score 1.0 by site policy (compare Copper Tripeptide-1). No counter-ion is part of the INCI name.
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
Glycine, histidine and lysine from fermentation, joined by peptide synthesis.
In plain English
A lab-made peptide built from three amino acids (glycine, histidine, lysine), related to the well-known copper peptide GHK, used to help condition skin. Sold here as a stabilised salt form.
CosIng definition: Glycine, oligomer with histidine and lysine
