What Is Lactococcus/Phaseolus Radiatus Seed Extract Ferment Filtrate?
Lactococcus/Phaseolus Radiatus Seed Extract Ferment Filtrate is a liquid obtained after mung bean seed extract is fermented by the probiotic bacterium Lactococcus. The process breaks down large plant compounds into smaller bioactive molecules such as peptides, amino acids, simple sugars and organic acids, all of which are prized for skin and scalp care. Fermentation also lowers the pH of the mixture, giving it a mild preservative effect.
Mung bean has long been valued in Asian beauty rituals for calming oily skin. Scientists paired it with Lactococcus cultures to amplify its benefits through fermentation, a technique borrowed from food science that gained traction in cosmetics in the early 2000s. The filtrate is produced by mixing an aqueous mung bean extract with the bacteria, letting it ferment under controlled temperature, then filtering out cellular debris to yield a clear, low-odor fluid that blends easily into water-based formulas.
You will find this ingredient in lightweight moisturizers, mattifying lotions, leave-on scalp tonics, clarifying hair masks, pre-shampoo treatments and targeted serums for blemish-prone skin. Its gentle nature makes it a popular choice for daily care products aimed at balancing oil while supporting the skin barrier.
Lactococcus/Phaseolus Radiatus Seed Extract Ferment Filtrate’s Cosmetic Benefits/Uses
This multitasking ferment brings several advantages to skin and hair care formulas:
- Anti-Seborrheic: helps reduce flaking and itching linked to oily scalp conditions, promoting a healthier scalp environment
- Anti-Sebum: moderates excess oil production on skin or scalp, leaving a fresher matte finish and extending the clean feel of hair
- Antimicrobial: introduces naturally occurring acids and peptides that curb the growth of odor-causing or blemish-triggering microbes, supporting clearer skin
- Hair Conditioning: deposits lightweight proteins and sugars that smooth the hair cuticle, improve manageability and enhance softness without heaviness
- Skin Conditioning: supplies humectants and soothing compounds that improve skin hydration, comfort and overall texture
Who Can Use Lactococcus/Phaseolus Radiatus Seed Extract Ferment Filtrate
This ferment suits most skin types but shines for oily, combination and blemish prone skin because it helps balance excess sebum. Normal skin can also benefit from its light hydration while sensitive skin generally tolerates it thanks to the mild pH and low fragrance profile. Very dry or eczema-prone skin may find it insufficiently emollient on its own and could prefer formulas that pair it with richer oils or butters.
The ingredient is produced from mung bean extract and probiotic bacteria with no animal derived components so it aligns with vegan and vegetarian preferences.
No research flags concerns for topical use during pregnancy or breastfeeding. The ferment remains on the outer skin layer with minimal chance of systemic absorption. Still, this is not medical advice and anyone who is pregnant or nursing should run new skincare products past a healthcare professional to be safe.
Lactococcus/Phaseolus Radiatus Seed Extract Ferment Filtrate is not known to cause photosensitivity so it can be worn day or night without raising sun sensitivity.
The filtrate is water soluble and plays well with most common skincare actives and preservatives which makes it easy to slot into existing routines without special precautions.
Potential Side Effects/Adverse Reactions
Side effects and reactions to topical Lactococcus/Phaseolus Radiatus Seed Extract Ferment Filtrate vary from person to person. The points below list potential issues only and most users will not experience them when the ingredient is formulated and used correctly.
- Mild stinging or burning
- Transient redness or flushing
- Itchiness or scalp tingling
- Allergic contact dermatitis in individuals sensitive to legumes or fermentation by-products
If any of these reactions occur discontinue use and consult a healthcare professional if irritation persists.
Comedogenic Rating
Rating: 0-1
This ferment filtrate is water based, contains no heavy oils or waxes and breaks larger plant molecules into smaller lightweight components. These factors mean it sits lightly on skin, is quickly absorbed and is very unlikely to clog pores. The slight range accounts for individual differences in skin response and the presence of natural sugars that could, in rare cases, trap debris if a formula is poorly preserved.
Overall it is considered safe for acne-prone or breakout-prone skin.
If combined with highly occlusive emollients in a finished product the overall formula, not the ferment itself, could raise the comedogenic potential so check the full ingredient list.
Summary
Lactococcus/Phaseolus Radiatus Seed Extract Ferment Filtrate offers anti-sebum, anti-seborrheic, antimicrobial, hair conditioning and skin conditioning benefits. Fermentation releases peptides, amino acids and organic acids that calm oil production, inhibit blemish-causing microbes, soothe irritation and lightly hydrate both skin and scalp. In hair care these micro nutrients coat the cuticle for smoother strands without weight.
While not a household name it is gaining traction in K-beauty inspired formulations and niche scalp treatments thanks to its gentle multi-tasking profile and vegan origin.
The ingredient has an excellent safety record with only rare reports of sensitivity. Still, skin is individual so give any new product a quick patch test before full use.
