How we scored it

Single defined polyphenol isolated from plant extraction; no synthetic fragment used commercially = 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

Isolated by extraction and purification from the root of Salvia miltiorrhiza (Danshen). No commercially significant chemical-synthesis route exists given its structural complexity.

In plain English

A polyphenol compound extracted from the root of Salvia miltiorrhiza (Chinese sage, also called Danshen). Used to condition and protect skin.
