How we scored it
Peptide built only from natural amino acids (Asp, Cys, Gly, Glu, His, Ile, Met, Ser, Tyr); coupling reagents leave no mass. 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
Made by solid-phase synthesis from fermentation-derived amino acids. No alternative commercial route changes this.
In plain English
A lab-assembled chain of natural amino acids used to help condition skin. Although it is manufactured, every building block comes from fermentation, so it counts as fully natural-origin.
CosIng definition: Decapeptide-5 is the synthetic peptide consisting of aspartic acid, cysteine, glycine, glutamic acid, histidine, isoleucine, methionine, serine and tyrosine
