What Is Lactobacillus/Phaseolus Angularis Seed Extract Ferment Extract Filtrate?
Lactobacillus/Phaseolus Angularis Seed Extract Ferment Extract Filtrate comes from the humble adzuki bean, a small red bean long valued in East Asian beauty rituals. The beans are first soaked and gently ground to pull out their natural proteins, sugars and minerals. This raw extract is then mixed with the friendly probiotic bacterium Lactobacillus. During a controlled fermentation the bacteria break down big molecules into smaller ones that skin can absorb more easily while also creating skin loving substances such as lactic acid, peptides and antioxidants. After fermentation the mixture is carefully filtered to remove solids, leaving a clear liquid—known as the filtrate—rich in active compounds yet light in texture.
The rise of fermented skincare in Korea and Japan during the early 2000s pushed this ingredient into mainstream cosmetic labs. Brands noticed that fermentation boosts the bean’s natural brightening and moisturizing properties while lowering the risk of irritation, making it appealing for modern formulas that aim to deliver visible results with a gentle touch.
You will most often spot this filtrate in brightening serums, hydrating essences, sheet masks, soothing gels, lightweight moisturizers and multi step anti aging treatments. Because it is water based and fairly stable it fits well into both leave on and rinse off products.
Lactobacillus/Phaseolus Angularis Seed Extract Ferment Extract Filtrate’s Cosmetic Benefits/Uses
This multitasking ferment brings several helpful actions to a skincare formula:
- Antioxidant: Helps neutralize free radicals generated by UV light and pollution which can otherwise speed up the look of aging
- Bleaching: Supports a more even skin tone by reducing the appearance of dark spots and post acne marks for a brighter complexion
- Humectant: Draws water from the air and deeper layers of the skin to the surface so skin feels plump and comfortable
- Skin Conditioning: Softens rough patches and improves overall texture giving skin a smoother healthier look
- Emollient: Adds a light layer of softness that helps seal in moisture without feeling heavy or greasy
Who Can Use Lactobacillus/Phaseolus Angularis Seed Extract Ferment Extract Filtrate
This ferment filtrate is generally friendly to all skin types including dry, normal, combination, oily and even sensitive skin because it is water light and low in irritants. The ingredient does not clog pores or leave an oily residue so acne prone users tend to tolerate it well. The only group that may need extra caution are people with known legume allergies since adzuki beans sit in the same botanical family as peanuts and soy.
The material is created from a plant source and cultured with the probiotic bacterium Lactobacillus so it contains no animal derived matter. That makes it suitable for vegans and vegetarians.
No studies have flagged special risks for pregnant or breastfeeding women. Still this is not medical advice and anyone who is expecting or nursing should ask their doctor before adding a new product to the routine.
Lactobacillus/Phaseolus Angularis Seed Extract Ferment Extract Filtrate is not known to increase photosensitivity. Standard daytime sunscreen habits remain advisable but there is no extra need to limit sun exposure solely because of this ingredient.
Potential Side Effects/Adverse Reactions
Reactions to topically applied Lactobacillus/Phaseolus Angularis Seed Extract Ferment Extract Filtrate vary from person to person. The points below outline potential but unlikely issues for most users when the ingredient is properly formulated.
- Localized redness or itching
- Mild stinging on freshly exfoliated or damaged skin

If any of these effects appear stop using the product and consult a healthcare professional
Comedogenic Rating
Rating: 0 / 5
This ferment filtrate is water based, contains no heavy oils or waxes and has molecules that are small enough to sink in quickly rather than sit on the surface and block pores. For those reasons it is considered non comedogenic.
That makes it a good match for people who are prone to acne or frequent breakouts.
Keep in mind that the finished product formula matters too. If the filtrate is blended with thick butters or high levels of silicones the overall product could still trigger clogged pores even though the ferment itself does not.
Summary
Lactobacillus/Phaseolus Angularis Seed Extract Ferment Extract Filtrate offers antioxidant protection, gentle brightening, moisture binding humectant action, skin softening conditioning and a light emollient feel. Fermentation breaks the adzuki bean nutrients into smaller parts and adds lactobacillus-derived peptides and mild acids so skin can soak up the benefits with little risk of irritation.
While not yet a household name it has been gaining steady attention in K-beauty and indie formulas thanks to its multitasking profile and skin friendly nature.
Overall safety data are reassuring. Most users experience no problems apart from rare legume related allergies. As with any new skincare ingredient it is smart to do a small patch test first to make sure your skin agrees with it before applying it more broadly.
