Ingredient review
Hydrolyzed Rice Ferment Filtrate
INCI: Lachancea/Hydrolyzed Rice Ferment Filtrate
A gentle, fermented rice ingredient that hydrates and supports skin barrier health without irritation.
In plain English
This ingredient is made by fermenting rice with a specific yeast called Lachancea. The fermentation process breaks down rice proteins into smaller, more absorbable pieces like amino acids and peptides. When applied to skin, it helps attract and hold moisture, supports the skin's natural barrier, and provides antioxidant protection. It's similar to sake ferment but milder and more focused on hydration.

Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Hydrolyzed Rice Ferment Filtrate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A biotech-derived ingredient created by fermenting hydrolyzed rice proteins with the yeast Lachancea, resulting in a filtrate rich in amino acids, peptides, organic acids, and antioxidants.
How it works
The small peptides and amino acids from the fermentation process act as humectants, drawing moisture into the skin. They also help support the skin barrier by providing building blocks for natural moisturizing factors. The organic acids produced during fermentation gently exfoliate and improve skin texture over time.
Pros
Gentle hydration
Provides moisture without the stickiness of some humectants, making it suitable for daily use in serums and toners.
Barrier support
The amino acids and peptides help reinforce the skin's natural barrier, which can reduce water loss and improve resilience.
Cons and cautions
Limited research
Most evidence comes from studies on rice ferments in general, not this specific Lachancea strain, so the exact benefits are less certain.
Potential allergen
Although rare, rice allergies exist, and this ingredient could trigger a reaction in sensitive individuals.
Best for
- People with dry or dehydrated skin looking for gentle hydration
- Those with sensitive skin who want a mild, non-irritating humectant
Use caution if
- Individuals with a known allergy to rice or fermented rice products
Usage tips
Safety summary
Hydrolyzed Rice Ferment Filtrate is considered safe for topical use with a low risk of irritation or clogging pores. Allergic reactions are rare but possible in individuals with rice sensitivity.
Research notes
Studies on rice ferments suggest benefits for hydration and barrier function, but direct evidence for this specific Lachancea ferment is limited. Most data come from in vitro and anecdotal reports.
Common label clues
- Typical concentration
- 1-10% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU; no specific restrictions.
- Common uses
- Serums, Toners, Essences, Moisturizers
- Environmental note
- Rice is a widely cultivated crop; fermentation is a low-energy process, making this ingredient relatively sustainable.
Good to know
- This ingredient is often found in K-beauty style essences and toners
- The fermentation process may increase the bioavailability of rice's natural nutrients
