How we scored it
Redox cofactor commercially produced by bacterial fermentation, consistent with this site's fermentation-product examples → 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
Pyrroloquinoline Quinone is produced commercially by bacterial fermentation, similar to other fermentation-derived cosmetic actives such as coenzyme Q10. A minor chemical-synthesis route also exists, so market-share confidence is limited.
In plain English
An antioxidant active that helps protect and condition skin. It is produced by fermenting bacteria, similar to how some vitamins and coenzymes are made.
CosIng definition: Pyrroloquinoline Quinone is the organic compound that conforms to the formula:
