Ingredient review
Quinoa Ferment Filtrate
INCI: LACTOBACILLUS/QUINOA FERMENT EXTRACT FILTRATE
A gentle, probiotic-derived ingredient that may help strengthen the skin barrier and improve hydration, though research is still emerging.
In plain English
This ingredient is made by fermenting quinoa with friendly bacteria (Lactobacillus). The fermentation process breaks down the quinoa into smaller, more skin-friendly molecules. When applied to skin, it can help support the skin's natural barrier and keep moisture in. Think of it as a gentle, nourishing food for your skin, similar to how probiotics support gut health.

What it is
A filtrate from the fermentation of quinoa seeds by Lactobacillus bacteria, containing peptides, amino acids, and other bioactive compounds.
How it works
The fermentation process creates smaller peptides and amino acids that can help support the skin's natural moisture barrier. It may also encourage the growth of beneficial skin microbes, promoting a balanced microbiome.
Pros
Gentle on skin
The fermentation process makes it less likely to cause irritation compared to raw plant extracts, making it suitable for sensitive skin types.
Supports skin barrier
The peptides and amino acids produced during fermentation can help strengthen the skin's natural moisture barrier, reducing water loss.
Cons and cautions
Limited research
Most evidence comes from lab studies or small trials; large-scale human studies are still needed to confirm long-term benefits.
Variable quality
The potency of the ferment can vary depending on the fermentation process and the specific strain of Lactobacillus used, leading to inconsistent results.
Best for
- Those with dry or dehydrated skin
- Anyone looking for gentle, probiotic skincare
Use caution if
- Individuals with known allergies to quinoa or fermented ingredients
