Ingredient review
Fermented Rice & Royal Jelly Complex
INCI: Bacillus/Monascus/Rice Bran/Royal Jelly Ferment Filtrate
A gentle fermented ingredient that may help hydrate and condition skin, but research is still emerging.
In plain English
This ingredient is made by fermenting rice bran and royal jelly with two types of bacteria (Bacillus and Monascus). The fermentation process breaks down the original materials into smaller, potentially more skin-friendly components. It's used in skincare products to help keep skin feeling soft, smooth, and hydrated. Think of it like a gentle, nutrient-rich broth for your skin.
Quick decision guide

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 filtrate obtained after fermenting rice bran and royal jelly with Bacillus and Monascus bacteria. The fermentation creates a complex mixture of amino acids, peptides, sugars, and other bioactive compounds.
How it works
The fermentation process breaks down proteins and carbohydrates into smaller molecules that may be more easily absorbed by the skin. These components can help attract and retain moisture (humectant effect) and support the skin's natural barrier function. The specific mechanisms are not fully understood, but it is generally considered a mild conditioning agent.
Pros
Gentle hydration
The fermentation process creates small molecules that can help attract moisture to the skin, making it feel softer and more supple without heavy oils.
Skin conditioning
It may help improve the overall feel and texture of the skin by supporting the skin's natural barrier, leaving it smooth and comfortable.
Cons and cautions
Limited evidence
Most benefits are based on traditional use and general knowledge of ferments, not on large-scale human studies for this specific blend.
Potential allergen
Royal jelly can cause allergic reactions in some people, especially those with pollen or bee sting allergies, so patch testing is wise.
Best for
- People looking for gentle hydration and skin conditioning
- Those interested in fermented skincare ingredients
Use caution if
- Individuals with known allergies to royal jelly or rice
Usage tips
Safety summary
This ingredient is considered safe for topical use in cosmetics. The fermentation process reduces the risk of irritation, but individuals with bee product allergies should exercise caution. Always patch test new products.
Research notes
Research on this specific ferment blend is limited. However, studies on other ferments (like galactomyces) show they can improve skin hydration and barrier function. More targeted studies are needed for this exact ingredient.
Common label clues
- Typical concentration
- Typically 1–10% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when formulated properly. Not a drug ingredient.
- Common uses
- Serums, Essences, Moisturizers, Toners
- Environmental note
- Fermentation is a relatively low-energy process, and rice bran is a byproduct of rice milling, making this ingredient potentially more sustainable.
Good to know
- Fermented ingredients are popular in K-beauty for their gentle, nourishing properties.
- The filtrate is the liquid left after removing solids, so it's a water-soluble ingredient.
