What Is Bacillus/Monascus/Capsella Bursa-Pastoris Leaf/Rice Bran Ferment Filtrate?
Bacillus/Monascus/Capsella Bursa-Pastoris Leaf/Rice Bran Ferment Filtrate is a fermented blend derived from shepherd’s purse leaves and rice bran. During production, the plant material is combined with two traditional fermentation microbes, Bacillus and Monascus, both well known in food fermentation. Over several days these microorganisms break down the leaves and bran, releasing peptides, amino acids, vitamins, fatty acids and antioxidant metabolites that are then filtered to create a clear liquid concentrate suitable for skin care.
The idea of using fermented botanicals in cosmetics traces back to East Asian beauty traditions where rice water and herbal ferments were prized for their skin softening effects. Modern labs adopted this concept, refining it with controlled microbial cultures to ensure consistency and safety. The resulting filtrate offers a natural cocktail of skin friendly compounds while limiting the need for synthetic preservatives.
After fermentation finishes, the mixture is pressed and passed through fine filters to remove solids and microbial residues. The filtrate is then standardized, tested for purity and blended into finished formulas. You will most often see this ingredient in hydrating essences, brightening serums, soothing sheet masks, lightweight moisturizers and anti aging creams where brands want a multifunctional plant ferment to boost overall performance.
Bacillus/Monascus/Capsella Bursa-Pastoris Leaf/Rice Bran Ferment Filtrate’s Cosmetic Benefits/Uses
This fermented filtrate delivers several skin care perks that make it a versatile formulating ally.
- Antimicrobial: Natural acids and peptides produced during fermentation help keep unwanted microbes at bay, supporting product preservation and promoting clearer looking skin.
- Antioxidant: The filtrate supplies polyphenols and vitamins that neutralize free radicals, helping to protect skin from environmental stress and premature aging.
- Skin Conditioning: Its mix of amino acids, sugars and minerals improves skin texture, leaving it feeling smoother and more supple.
- Emollient: Lightweight lipids from rice bran add a soft, comforting finish that reduces dryness without a greasy feel.
Who Can Use Bacillus/Monascus/Capsella Bursa-Pastoris Leaf/Rice Bran Ferment Filtrate
This ferment is generally suitable for all skin types including dry, normal, combination and oily skin because it offers lightweight hydration without a heavy residue. Sensitive skin users often tolerate it well thanks to its soothing amino acids, though anyone with a known allergy to rice or fermented ingredients should proceed cautiously.
The ingredient is plant and microbe derived with no animal by-products so it is considered appropriate for both vegans and vegetarians.
No data suggests that topical use poses a specific risk to women who are pregnant or breastfeeding, but this is not medical advice. Expectant or nursing mothers should show any new skincare product to their doctor before adding it to their routine just to be on the safe side.
Bacillus/Monascus/Capsella Bursa-Pastoris Leaf/Rice Bran Ferment Filtrate does not make skin more sensitive to the sun and can be used year round alongside regular daily sunscreen.
Potential Side Effects/Adverse Reactions
Side effects from topical Bacillus/Monascus/Capsella Bursa-Pastoris Leaf/Rice Bran Ferment Filtrate vary from person to person. The issues listed below are only potential effects and are unlikely for most users when the ingredient is formulated and stored correctly.
- Irritation: Mild redness stinging or itching may appear on very reactive skin especially if the product also contains other active ingredients
- Allergic contact dermatitis: Rare but possible for individuals allergic to rice plant compounds or fermentation by-products
- Breakouts: Congested or acne-prone skin could notice temporary blemishes if the finished formula also includes occlusive oils that trap debris
- Interaction with highly acidic products: Layering immediately after strong exfoliating acids might amplify tingling or dryness in sensitive users
If you experience any unwanted reaction stop using the product and consult a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 1/5
This ferment filtrate is mostly composed of water soluble peptides, amino acids and small amounts of lightweight rice bran lipids. These components are unlikely to block pores, giving it a very low comedogenic profile. While any ingredient can cause issues when paired with heavy occlusives, the filtrate itself is suitable for people prone to acne or breakouts.
Formulas that combine the filtrate with rich butters or waxes could raise the overall pore-clogging risk, so checking the full ingredient list still matters.
Summary
Bacillus/Monascus/Capsella Bursa-Pastoris Leaf/Rice Bran Ferment Filtrate acts as an antimicrobial, antioxidant, skin-conditioning and emollient agent. Fermentation breaks down shepherd’s purse leaves and rice bran, releasing peptides, vitamins, polyphenols and gentle lipids that help fend off microbes, neutralize free radicals, soften skin and lightly moisturize.
Although not a household name, the rise of fermented skincare has boosted its presence in essences and serums aimed at hydration and barrier support. It is generally considered safe for all skin types with few reported adverse effects. As with any new skincare addition it is wise to perform a quick patch test to make sure your skin agrees with it.
