What Is Lactobacillus/Cudrania Tricuspidata Bark Extract Ferment Filtrate?
Lactobacillus/Cudrania Tricuspidata Bark Extract Ferment Filtrate is an ingredient made by fermenting the bark of the Cudrania tricuspidata tree with the friendly bacterium Lactobacillus. Cudrania tricuspidata, sometimes called silkworm thorn or cudrang, grows mainly in East Asia and has long been valued in traditional skin care for its soothing properties. When its bark is placed in a controlled environment with Lactobacillus, the microorganisms break down large plant molecules into smaller ones that skin can absorb more easily. After fermentation the mixture is filtered, leaving behind a lightweight liquid rich in beneficial compounds such as polyphenols, flavonoids and amino acids. This filtrate first appeared in Korean beauty formulas looking for natural ferment-based actives and quickly spread to serums, sheet masks, lightweight moisturizers, anti aging creams and brightening essences because of its gentle yet effective profile.
Lactobacillus/Cudrania Tricuspidata Bark Extract Ferment Filtrate’s Cosmetic Benefits/Uses
This fermented bark filtrate supports skin in two key ways
- Antioxidant: The ferment is packed with plant polyphenols and flavonoids that help neutralize free radicals produced by sun exposure and pollution. By reducing oxidative stress it can help keep skin looking fresher and more even toned
- Skin conditioning: Fermentation releases amino acids and sugars that attract moisture and soften the outer layer of skin. Regular use can leave the complexion feeling smoother, calmer and better hydrated
Who Can Use Lactobacillus/Cudrania Tricuspidata Bark Extract Ferment Filtrate
This gentle ferment is generally well tolerated by all skin types. Dry or mature complexions appreciate the extra hydration while oily or breakout-prone skin benefits from the lightweight non-greasy texture. Sensitive skin usually finds it calming thanks to the reduced molecule size created during fermentation. There are no known reasons for extremely dry or severely compromised skin to avoid it, yet anyone with a history of plant-based allergies should read the label carefully for additional botanicals in the formula.
The ingredient comes from plant bark that has been fermented with a probiotic bacterium and contains no animal by-products, so most formulations are suitable for both vegetarians and vegans. Brands that certify their growth media as plant based can state this clearly on packaging.
No specific warnings exist for pregnant or breastfeeding women however scientific data is limited. This content is not medical advice and anyone who is expecting or nursing should show the product to a healthcare professional before adding it to a routine.
Lactobacillus/Cudrania Tricuspidata Bark Extract Ferment Filtrate does not make skin more sensitive to sunlight. Daily sunscreen use is still recommended as part of any healthy skincare regimen but extra precautions are not needed solely because of this ingredient.
Potential Side Effects/Adverse Reactions

- Mild redness or warmth
- Temporary stinging on very compromised skin
- Allergic contact dermatitis in individuals sensitive to mulberry family plants
- Breakouts if combined with highly occlusive bases in those prone to acne

Comedogenic Rating
Rating: 0–1. Lactobacillus/Cudrania Tricuspidata Bark Extract Ferment Filtrate is a water-light liquid with virtually no fatty acids or heavy waxes, so it does not have the kind of large oily molecules that can block pores. Fermentation further breaks down plant matter into smaller fragments that rinse away easily and sit weightlessly on skin. Because of that it is considered non-comedogenic or at worst very low on the scale. This makes it a comfortable choice for people prone to acne or frequent breakouts. Only the finished product’s other ingredients, such as thick butters or occlusive silicones, would change how pore-friendly the overall formula feels.
Summary
Lactobacillus/Cudrania Tricuspidata Bark Extract Ferment Filtrate serves mainly as an antioxidant and skin-conditioning agent. The bark supplies polyphenols and flavonoids that mop up free radicals while fermentation by Lactobacillus unlocks amino acids and sugars that boost moisture and soothe irritation. Although still a niche active outside of Korean beauty circles, its gentle profile and plant-probiotic story are helping it gain traction in serums, essences and light creams.
Current data and user experience suggest it is a very safe ingredient for most skin types, including sensitive and acne-prone. As with any new skincare addition, doing a small patch test first is a smart way to rule out personal sensitivities before full-face use.
