What Is Lactobacillus/Saccharomyces/Cnidii Rhizoma Root Ferment Filtrate?
Lactobacillus/Saccharomyces/Cnidii Rhizoma Root Ferment Filtrate starts with the roots of Cnidii rhizoma, a traditional East Asian herbal plant prized for its soothing power. The roots are washed, chopped and submerged in a nutrient solution, then inoculated with friendly Lactobacillus bacteria and Saccharomyces yeast. Over several days these microbes break down the root material, releasing low-molecular-weight peptides, amino acids, natural sugars, antioxidants, vitamins and trace minerals. Once fermentation is complete the mixture is carefully filtered to remove solids, leaving a clear, lightweight liquid rich in skin-loving compounds.
Fermented botanicals rose to fame through Korean beauty, where they are valued for being both gentle and highly active. The combination of an herbal root long used in folk skin care with modern probiotic fermentation caught formulators’ attention in the early 2010s. Today the filtrate is added to hydrating essences, brightening serums, sheet masks, lightweight moisturizers, barrier-repair creams, after-sun gels and even scalp tonics where a fast-absorbing antioxidant boost is desired.
Lactobacillus/Saccharomyces/Cnidii Rhizoma Root Ferment Filtrate’s Cosmetic Benefits/Uses
This multitasking ferment brings several perks to topical formulas
- Antioxidant: Supplies polyphenols and vitamins that help neutralize free radicals generated by UV light and pollution, supporting a more even tone and delaying visible signs of aging
- Skin conditioning: Fermentation creates small molecules that sink in quickly, delivering hydration and smoothing rough patches so skin feels soft and looks plump
- Skin protecting: Forms a breathable film that reinforces the moisture barrier and helps shield against daily environmental stress, making skin less prone to redness or tightness
Who Can Use Lactobacillus/Saccharomyces/Cnidii Rhizoma Root Ferment Filtrate
This ferment filtrate is considered friendly for most skin types. Its light watery texture suits oily and combination skin, while the natural humectants help relieve dryness or flaking so dry skin can enjoy it too. Sensitive skin often tolerates it well because fermentation reduces the chance of harsh residues. There are no known reasons for acne-prone or mature skin to avoid it, although very reactive skin should introduce any new active slowly.
The ingredient is sourced from a plant root and fermented with non-animal microbes, so it meets vegan and vegetarian standards. No animal by-products are used at any stage of production.
Current data does not flag any issues for women who are pregnant or breastfeeding when the filtrate is used topically. Still, this is not medical advice and anyone expecting or nursing should ask a qualified health professional before adding new skincare products.
The filtrate is not known to cause photosensitivity, so you can use it day or night without raising the risk of sun burn. Normal sunscreen habits should still be followed. No other notable restrictions or incompatibilities are documented.

Comedogenic Rating
Rating: 0 (non-comedogenic)
This ferment filtrate is a thin water-like fluid with virtually no oils, waxes or fatty acids that could clog pores. Its key components are small peptides, amino acids, sugars and antioxidants that dissolve completely in water and rinse away easily. Because it lacks heavy lipids the risk of it blocking follicles is extremely low even when layered under richer products.
That makes Lactobacillus/Saccharomyces/Cnidii Rhizoma Root Ferment Filtrate suitable for skin that is prone to acne or frequent breakouts.
As always overall pore-friendliness depends on the entire formula, so check the other ingredients in your product if congestion is a concern.
Summary
Lactobacillus/Saccharomyces/Cnidii Rhizoma Root Ferment Filtrate works as an antioxidant, skin-conditioning and skin-protecting agent. Fermentation breaks the Cnidii root down into micro-nutrients that mop up free radicals, attract and hold water then form a light breathable shield that helps the skin barrier stay calm and resilient.
While not as famous as galactomyces or kombucha ferments, this ingredient has been gaining quiet popularity in K-beauty style essences, barrier creams and after-sun gels thanks to its gentle feel and quick results.
Available research and real-world use point to a very safe profile with only rare irritation reports. Still, whenever you introduce a new product you should patch test first to make sure your skin agrees with the complete formula.
