Ingredient review
Persimmon Ferment Filtrate
INCI: Pediococcus/Diospyros Kaki Fruit Ferment Filtrate
A gentle fermented fruit extract that may help protect skin from environmental stress, though research is still developing.
In plain English
This ingredient is made by fermenting persimmon fruit with Pediococcus bacteria. Fermentation can break down fruit compounds into smaller, potentially more skin-friendly molecules. It's thought to provide antioxidant benefits, meaning it may help neutralize some of the damage caused by pollution and UV exposure, but it's not a sunscreen or a cure-all.

What it is
A fermented filtrate derived from persimmon fruit (Diospyros kaki) using Pediococcus bacteria. The fermentation process creates a liquid rich in bioactive compounds like polyphenols and flavonoids.
How it works
In a cosmetic product, it acts mainly as an antioxidant, helping to scavenge free radicals that can lead to premature skin aging. It also functions as a skin-conditioning agent, which means it can help keep the skin feeling soft and smooth.
Pros
