Ingredient review
Fermented Perilla & Rice Bran Complex
INCI: BACILLUS/MONASCUS/PERILLA OCYMOIDES SPROUT/RICE BRAN FERMENT FILTRATE
A fermented blend of perilla sprout and rice bran that may offer antioxidant and skin-soothing benefits, though human research is limited.
In plain English
This ingredient is made by fermenting perilla sprout (a plant in the mint family) and rice bran with beneficial bacteria and yeast. The fermentation process breaks down the plant materials into smaller, potentially more absorbable compounds. In skincare, it's used as a gentle antioxidant and skin conditioner, meaning it may help protect skin from environmental stress and keep it feeling soft. Because it's a complex mixture, its exact effects can vary by batch and formulation.
Quick decision guide
Useful, but context matters

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 Perilla ocymoides sprout and rice bran with Bacillus and Monascus microorganisms. It contains a mix of peptides, amino acids, and plant-derived antioxidants.
How it works
The fermentation process creates bioactive peptides and antioxidants that may help neutralize free radicals and support the skin's natural barrier. The filtrate is thought to provide mild hydration and conditioning without heavy oils or synthetic additives.
Pros
Gentle antioxidant support
The fermentation process may enhance the bioavailability of plant antioxidants, offering mild protection against daily environmental damage without irritation.
Barrier-friendly conditioning
As a skin conditioner, it helps maintain a soft, smooth feel on the skin, which can be especially beneficial for dry or compromised barriers.
Cons and cautions
Limited human research
Most evidence comes from lab or animal studies; well-controlled human trials on this specific ferment blend are scarce, so its real-world benefits are not fully proven.
Batch variability
Because it's a natural ferment, the exact composition can differ between batches, leading to inconsistent performance in skincare products.
Best for
- People looking for a gentle, fermented antioxidant ingredient
- Those with normal to dry skin wanting extra barrier support
Use caution if
- Individuals with known allergies to perilla or rice (rare but possible)
Usage tips
Safety summary
Considered safe for topical use in cosmetics. The low irritation and comedogenic risk make it suitable for most skin types, though those with rare plant allergies should patch test.
Research notes
Evidence is primarily from in vitro studies showing antioxidant and anti-inflammatory potential. Human data is limited, and more research is needed to confirm efficacy in skincare.
Common label clues
