How we scored it

3-residue peptide (glycine, serine, valine); amino acids are natural building blocks = 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

Synthesized by joining glycine, serine and valine, all fermentation- or hydrolysate-derived amino acids. No petrochemical mass remains in the final peptide.

In plain English

A small chain of three amino acids built up in a lab from natural amino-acid building blocks. Used in skin care as a conditioning ingredient.

CosIng definition: Tripeptide-3 is a synthetic peptide containing glycine, serine and valine residues
