How we scored it

Flavonol aglycone; cosmetic-grade material is extracted/purified from plant sources, 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 Sophora japonica buds or other flavonoid-rich botanicals. Total synthesis exists but is not the typical commercial route.

In plain English

An antioxidant flavonoid found in many fruits and vegetables, used to condition skin. Cosmetic-grade material is extracted and purified from plant sources.
