How we scored it
Ferment filtrate extract: perilla leaf and lactic-acid-bacteria metabolites, all n=1; solvents and media additives ignored. 100% / 100% = 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
Dominant route is fermentation of perilla (Perilla frutescens) leaves with Lactobacillus, followed by extraction and filtration. No commercially significant non-biological route exists.
In plain English
A liquid made by fermenting perilla (shiso) leaves with Lactobacillus bacteria, then extracting and filtering the result. It is used in skin-care products as an antioxidant and an antimicrobial ingredient. It comes from perilla leaves and bacterial fermentation.
