What Is Lachancea/Hydrolyzed Rice Ferment Filtrate?
Lachancea/Hydrolyzed Rice Ferment Filtrate comes from rice that has been broken down into smaller pieces, then fermented with a friendly yeast named Lachancea. During fermentation this yeast releases enzymes and natural moisturizers, creating a liquid rich in amino acids, sugars, vitamins and minerals that skin can easily recognize. The idea of using rice ferment stems from long-standing beauty rituals in East Asia where bathwater from rinsed rice was prized for its skin-softening effect. Modern laboratories took that folk wisdom, paired it with controlled fermentation and developed a stable filtrate ready for skin care labs.
The process starts with rice grains that are enzymatically hydrolyzed to make a nutrient-dense slurry. Lachancea yeast is added and allowed to ferment under carefully managed temperature and pH conditions. Once fermentation is complete, the mixture is filtered to remove solids and yeast cells, leaving a clear lightweight liquid. This filtrate is then standardized and preserved before being shipped to cosmetic manufacturers.
You will spot Lachancea/Hydrolyzed Rice Ferment Filtrate in a variety of leave-on and rinse-off products including hydrating toners, sheet masks, essence-style boosters, lightweight moisturizers, soothing after-sun gels and brightening serums. Formulators also add it to anti-aging blends because its natural sugars help plump the surface and improve the feel of mature or dehydrated skin.
Lachancea/Hydrolyzed Rice Ferment Filtrate’s Cosmetic Benefits/Uses
This multitasking ferment brings more than one perk to the formula.
- Humectant – attracts water from the air and pulls it into the top layers of skin so the complexion feels fresh and looks dewy
- Skin conditioning – smooths rough patches supports a softer touch and can help other actives glide on more evenly
Who Can Use Lachancea/Hydrolyzed Rice Ferment Filtrate
Because it is a lightweight water based humectant this ferment suits almost every skin type. Dry and dehydrated skin gain extra moisture while oily or combination skin appreciate the non-greasy feel. Sensitive skin usually tolerates it well since the filtrate is free of added fragrance and harsh solvents. The only group that may need extra caution is anyone with a known allergy to rice or yeast proteins as trace amounts could linger in the filtrate.
The ingredient is plant and microorganism derived with no animal input so it is considered friendly for both vegans and vegetarians.
No data suggests a particular risk for women who are pregnant or breastfeeding. Still this is not medical advice and anyone expecting or nursing should run the full product list past a doctor before use.
Lachancea/Hydrolyzed Rice Ferment Filtrate does not increase photosensitivity so standard daytime sun care is all that is needed.
Potential Side Effects/Adverse Reactions
Side effects from topical use can vary from person to person. The points below list potential reactions although most users will not experience them when the ingredient is properly formulated and used as directed.
- Mild redness or warmth
- Temporary stinging on very compromised skin
- Itching linked to yeast or rice sensitivity
- Allergic contact dermatitis in rare cases
- Flare of yeast related acne in individuals highly prone to fungal breakouts
If any of these reactions occur discontinue use and consult a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 0-1 out of 5. Lachancea/Hydrolyzed Rice Ferment Filtrate is a thin water based liquid with no fatty oils or heavy waxes that could block pores. Its main components are lightweight humectant sugars, amino acids and minerals which sit on the surface then rinse or evaporate without leaving a greasy film. Because of that, it is very unlikely to clog pores so it is generally safe for skin that breaks out easily.
People who struggle with fungal acne sometimes watch for fermented ingredients, yet this filtrate is used at low levels and is not an oil source for Malassezia so most find it acceptable. As always the full formula matters if the product also contains richer oils.
Summary
Lachancea/Hydrolyzed Rice Ferment Filtrate acts mainly as a humectant and skin conditioner. The yeast driven fermentation breaks rice proteins into small molecules that pull water toward the skin surface, soften rough spots and give a quick plumping effect. These same lightweight sugars help other actives spread smoothly so formulas feel silky instead of sticky.
The ferment is gaining popularity in toners, essences and gel moisturizers, especially in K-beauty inspired lines that focus on gentle hydration. It is still a niche ingredient compared with classics like glycerin or hyaluronic acid but more brands are adding it each year.
Current safety data and long standing food and topical use of rice and yeast suggest a low risk profile with only rare allergy concerns. Still every skin is different so do a small patch test when trying any new product to make sure it plays nicely with your skin.
