What Is Bacillus/Monascus/Vanda Coerulea Callus/Rice Bran Ferment Filtrate?
Bacillus/Monascus/Vanda Coerulea Callus/Rice Bran Ferment Filtrate is a liquid collected after fermenting two plant materials—rice bran and callus cells from the blue vanda orchid—using two friendly microorganisms, Bacillus and Monascus. During fermentation these microbes break the plant matter down and release helpful molecules such as amino acids, peptides, vitamins and natural oils. The finished filtrate is then clarified to remove solids leaving behind a lightweight fluid packed with skin-loving nutrients.
Fermentation has a long history in beauty, inspired by traditional foods like kimchi and sake where the process boosts nutrient levels. Cosmetic chemists adopted the same idea in the last couple of decades to create gentle yet potent ingredients. Combining rice bran, known for its soothing fatty acids, with the rare orchid adds a touch of luxury while Monascus and Bacillus fine-tune the mix during fermentation.
The filtrate is produced in a controlled tank where rice bran and orchid callus cells are mixed with the microorganisms, kept at steady warmth and pH, then filtered and preserved. Because the process is water based and mild it suits clean beauty trends and eco-friendly lines.
You will usually spot this ingredient in lightweight moisturizers, balancing serums, anti-aging emulsions, sheet masks and leave-on treatments aimed at oily or combination skin.
Bacillus/Monascus/Vanda Coerulea Callus/Rice Bran Ferment Filtrate’s Cosmetic Benefits/Uses
This fermented filtrate brings several useful actions to a skincare formula
- Anti-Sebum: Helps regulate excess oil on the skin surface which can reduce shine and the look of enlarged pores. This makes products feel lighter and keeps makeup from sliding off
- Skin Conditioning: Supplies amino acids and antioxidants that soften skin improve texture and support a healthy moisture barrier so skin feels smooth and comfortable
- Emollient: Adds a light layer of lipids that fill tiny gaps between skin cells. This locks in water and leaves the complexion supple without a greasy finish
Who Can Use Bacillus/Monascus/Vanda Coerulea Callus/Rice Bran Ferment Filtrate
This filtrate suits most skin types. Its oil balancing ability is ideal for oily and combination skin while the lightweight emollient action keeps normal skin comfortable. Dry or very dry complexions can still benefit when the filtrate is paired with richer creams though on its own it may not supply enough lipids for severely parched skin. The ingredient is generally gentle so sensitive skin users often tolerate it, but those with known allergies to fermented rice products should stay alert.
The material is produced from plant cells, rice bran and naturally occurring microorganisms with no animal derivatives which makes it appropriate for vegans and vegetarians.
No data suggest any risk to pregnant or breastfeeding women when the filtrate is used topically at the tiny levels found in cosmetics. It does not penetrate deeply or interfere with hormones. That said this is not medical advice and anyone expecting or nursing should run any skincare choice by a qualified doctor to be safe.
Bacillus/Monascus/Vanda Coerulea Callus/Rice Bran Ferment Filtrate does not cause photosensitivity. Users can apply it morning or night without increasing sunburn risk though daily sunscreen is still recommended for overall skin health.
Potential Side Effects/Adverse Reactions
Responses to topical Bacillus/Monascus/Vanda Coerulea Callus/Rice Bran Ferment Filtrate vary from person to person. The points below list potential side effects, most of which are rare when the ingredient is formulated and preserved correctly.
- Mild redness or stinging especially on very reactive skin
- Allergic contact dermatitis in individuals sensitive to rice proteins or fermentation by products
- Pimple flare-up if the product formula also contains heavy occlusives that trap oil
- Itching or dryness when used in high concentrations without supporting hydrators
- Spoilage related irritation if a poorly preserved product becomes contaminated
If any of these reactions occur stop using the product and seek advice from a healthcare professional.
Comedogenic Rating
Rating: 1 out of 5
The filtrate is mostly water based and contains only trace amounts of rice bran lipids so it rarely clogs pores. Any fatty acids present are balanced by the ingredient’s mild oil regulating effect which can actually help keep pores clearer. Because of the minimal lipid load and lightweight texture it is generally considered suitable for people who are prone to acne or breakouts.
No published data point to the filtrate increasing comedone formation even when used daily. Of course the overall formula matters; pairing it with heavy waxes or butters can still cause congestion so always look at the full ingredient list.
Summary
Bacillus/Monascus/Vanda Coerulea Callus/Rice Bran Ferment Filtrate serves three main roles in skincare: it helps curb excess sebum, conditions the skin with amino acids antioxidants and vitamins and adds a light emollient layer that smooths and softens. Fermentation breaks down rice bran and orchid callus cells into smaller bioactive molecules making them easier for skin to use while keeping the ingredient gentle.
The filtrate is still a niche addition most often spotted in K-beauty inspired serums masks and oil control moisturizers yet its clean origin story and multitasking nature are winning it more fans each year.
Current research and user experience label it as a low risk ingredient with few reported adverse effects. Even so every skin is unique so perform a quick patch test when trying any new product that features this ferment just to be safe.
