What Is Bacillus/Ganoderma Lucidum/Soybean Extract Ferment Filtrate?
Bacillus/Ganoderma Lucidum/Soybean Extract Ferment Filtrate is a fermented blend that starts with three natural materials: Bacillus bacteria, Ganoderma lucidum mushroom and soybeans. When these are combined under controlled warmth and moisture the Bacillus breaks down proteins, sugars and other nutrients from the mushroom and soy. The liquid that remains after the solids are filtered out is the “ferment filtrate.” It is rich in small peptides, amino acids, fatty acids and antioxidant compounds that skin and hair can easily take up.
The idea of using fermented ingredients in beauty products is not new. Traditional Asian skin care has long valued fermented rice water for its smoothing effect. Building on that heritage, labs began experimenting with other plant and fungi sources in the 1990s. Ganoderma lucidum, often called reishi, was prized in herbal traditions for its calming and antioxidant profile. When scientists mixed it with soy and a friendly Bacillus strain they found the resulting filtrate helped balance oil and soften hair, opening the door for its modern cosmetic use.
Production follows food-grade standards. First, soybeans are soaked and steamed. Ganoderma lucidum powder is added along with the Bacillus culture. The mixture ferments for several days, is gently heated to stop microbial activity then pressed and filtered. The clear liquid is preserved and standardized so every batch delivers the same skin-friendly properties.
You will most often see this ingredient in lightweight moisturizers, balancing toners, leave-on scalp treatments, anti-pollution serums, sheet masks and shine-boosting hair conditioners.
Bacillus/Ganoderma Lucidum/Soybean Extract Ferment Filtrate’s Cosmetic Benefits/Uses
This multitasking ferment brings several perks to skin and hair care formulas.
- Anti-Sebum: Helps regulate excess oil on the skin surface so the complexion looks fresher and makeup lasts longer
- Hair Conditioning: Smooths the cuticle, adds slip and makes strands feel softer without weighing them down
- Emollient: Provides a light moisture layer that reduces dryness and leaves skin feeling supple
Who Can Use Bacillus/Ganoderma Lucidum/Soybean Extract Ferment Filtrate
This ferment suits most skin types. Oily and combination skin tend to enjoy its oil balancing quality while normal and dry skin gain a light layer of moisture. Very dry or compromised skin might need a richer companion ingredient because the filtrate itself is lightweight and may not deliver enough nourishment on its own.
The blend is plant based and produced without animal derived materials so it is generally considered suitable for both vegans and vegetarians.
No specific data suggest a risk for pregnant or breastfeeding women when the ingredient is used topically in cosmetic amounts. Still, this is not medical advice. Anyone who is expecting or nursing should show the product to a doctor before adding it to a routine just to be safe.
The filtrate is not known to increase sun sensitivity. Usual daily sunscreen habits are still recommended but there is no extra need for precaution related to this ingredient.
Potential Side Effects/Adverse Reactions
Responses to topical Bacillus/Ganoderma Lucidum/Soybean Extract Ferment Filtrate differ from person to person. The points below outline potential issues that could occur, though they are uncommon when the ingredient is properly formulated and used as directed.
- Skin redness or stinging in those with very sensitive skin
- Itching or rash in people who have existing soy or mushroom allergies
- Mild irritation if applied to broken or freshly exfoliated skin
- Rare acne flare if combined with heavy occlusive products on highly clog prone skin
- Reaction to a contaminated or expired product resulting in burning or swelling
If any discomfort or visible reaction appears stop using the product and seek guidance from a healthcare professional.
Comedogenic Rating
Rating: 1/5. The filtrate is mostly water, small peptides and lightweight fatty acids so it does not form a heavy film on skin. It absorbs quickly and leaves little residue, making clogged pores unlikely for most users.
Because the rating is low it is generally fine for acne-prone or breakout-prone skin, especially when used in gel or fluid formulas.
Formulas that pair the ferment with thick butters or waxes could raise the overall comedogenicity of the finished product, so check the full ingredient list if you are highly sensitive.
Summary
Bacillus/Ganoderma Lucidum/Soybean Extract Ferment Filtrate works as an anti-sebum agent by helping the skin surface stay balanced, as a hair conditioner by smoothing the cuticle and as a light emollient that slips moisture into skin without heaviness. These effects come from the mix of amino acids, fatty acids and antioxidants created during fermentation, which are small enough for skin and hair to take up easily.
The ingredient sits in the rising wave of fermented actives popularized by Korean skin care but it is still a niche choice compared with classics like niacinamide. Brands use it when they want a gentle plant-based booster that feels fresh, not greasy.
Safety data and user reports show a low risk of irritation when it is formulated and stored correctly. Still, every person’s skin is different so it is smart to do a quick patch test before adding any new product with this ferment to your routine.
