How we scored it
Flavonol aglycone; cosmetic-grade material is extracted/purified from plants (e.g. bayberry bark), not totally synthesised, so the whole molecule counts as natural.
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
Purified by extraction from plants such as Myrica (bayberry) bark or other flavonoid-rich botanicals. Total synthesis exists but is not the typical commercial route.
In plain English
An antioxidant flavonoid found in berries, bark and vegetables, used in skin care. It's extracted and purified from plant sources rather than chemically synthesised.
