Ingredient review
Fermented Rice & Lotus Complex
INCI: (ASPERGILLUS/SACCHAROMYCES)/RICE FERMENT/BARLEY GRAIN MEAL/NELUMBO NUCIFERA FLOWER EXTRACT FERMENT EXTRACT FILTRATE
A fermented botanical blend that may help hydrate and soothe skin, but research on this exact mixture is limited.
In plain English
This ingredient is a fermented mixture of rice, barley, and lotus flower. Fermentation breaks down large molecules into smaller ones, which may make them easier for skin to absorb. It's used in skincare to provide gentle hydration and antioxidant benefits, but because it's a complex blend, its exact effects depend on the specific formulation.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A fermented extract made by culturing Aspergillus and Saccharomyces (types of fungi and yeast) on a mixture of rice, barley meal, and lotus flower extract. The fermentation process creates a liquid rich in amino acids, peptides, and other skin-friendly compounds.
How it works
The fermentation process breaks down proteins and carbohydrates into smaller, more bioavailable molecules. These can help attract and retain moisture in the skin (humectant effect) and may support the skin's natural barrier. The lotus flower component adds antioxidant properties that can help protect skin from environmental stressors.
Pros
Gentle hydration
The ferment provides moisture without heavy oils, making it suitable for most skin types, including oily and combination skin.
Antioxidant support
Lotus flower extract adds antioxidant benefits that may help protect skin from daily environmental stressors like pollution.
Cons and cautions
Limited research
There are few peer-reviewed studies on this exact multi-ingredient ferment, so its benefits are based on general knowledge of fermentation and individual components.
Variable effectiveness
Because it's a complex blend, its performance can vary significantly between different product formulations and concentrations.
Best for
- People looking for gentle, hydrating ingredients
- Those interested in fermented skincare for barrier support
Use caution if
- Individuals with known allergies to rice, barley, or lotus
- Those with very sensitive skin who react to fermented ingredients (patch test recommended)
Usage tips
Safety summary
This ingredient is considered safe for topical use in cosmetics. The fermentation process is controlled to prevent contamination. As with any botanical blend, there is a low risk of allergic reaction, so patch testing is wise for sensitive individuals.
Research notes
Research on fermented rice and lotus extracts individually suggests potential for hydration and antioxidant activity. However, no specific clinical studies on this exact multi-ferment blend were found. Evidence is emerging and based on traditional use and ingredient-level data.
