How we scored it
Oligomer of lysine, serine and threonine; amino acid building blocks are natural and condensation loses only water = 1.0.
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 fermentation-derived amino acids (lysine, serine, threonine) into a short peptide oligomer. No petrochemical fragment remains in the product regardless of chain length.
In plain English
A short peptide built from three amino acids, used in skincare to help condition the skin.
CosIng definition: Lysine, oligomer with serine and threonine
