What Is Bacillus/Chrysanthemum Zawadskii Extract Ferment Filtrate?
Bacillus/Chrysanthemum Zawadskii Extract Ferment Filtrate comes from the white or yellow chrysanthemum plant, Chrysanthemum zawadskii, a flower long valued in East Asia for calming teas and traditional skin soothers. Cosmetic chemists take an extract of the blossoms then let a friendly soil-dwelling bacterium called Bacillus work on it through a controlled fermentation process. During fermentation the microbe breaks large plant molecules into smaller ones that can sink into skin more easily and also releases skin-loving amino acids, peptides and sugars. After the brew is complete, the mixture is filtered to remove solids leaving a clear liquid concentrate rich in these new bioactive compounds.
The first fermented flower extracts began appearing in Korean skin care in the early 2010s, riding the interest in both probiotics and botanical actives. Brands found that fermentation could boost the soothing power of familiar herbs without harsh solvents. Today Bacillus/Chrysanthemum Zawadskii Extract Ferment Filtrate shows up in hydrating toners, sheet masks, lightweight lotions, anti-aging creams and post-sun repair gels where a gentle plant-based conditioner is desired.
Bacillus/Chrysanthemum Zawadskii Extract Ferment Filtrate’s Cosmetic Benefits/Uses
This ingredient is prized for one key role in modern formulas.
Skin conditioning: The filtrate softens rough patches, supports the skin barrier and leaves the surface feeling smooth and moist. The amino acids and sugars produced during fermentation attract water to the upper layers of skin while the flower-derived antioxidants help calm redness from everyday stressors. In a finished product this means a healthier-looking complexion that feels supple and comfortable after each use.
Who Can Use Bacillus/Chrysanthemum Zawadskii Extract Ferment Filtrate
This fermented flower filtrate is gentle enough for most skin types. Dry, normal, combination and sensitive skin often appreciate the extra hydration and soothing antioxidants. Oily or acne-prone skin can usually tolerate it as well because the ingredient is lightweight and non-pore-clogging, though choosing an overall formula with a light texture is still important.
The ingredient is derived from a plant and a naturally occurring bacterium with no animal by-products, so it is considered suitable for both vegans and vegetarians unless the finished product adds non-vegan additives.
No specific warnings exist for women who are pregnant or breastfeeding when this filtrate is applied topically. That said this is not medical advice and expecting or nursing mothers should check with their doctor before introducing any new skincare product just to be safe.
Bacillus/Chrysanthemum Zawadskii Extract Ferment Filtrate does not increase photosensitivity and can be used morning or night without making skin more prone to sun damage.

Comedogenic Rating
Rating: 1 / 5
Bacillus/Chrysanthemum Zawadskii Extract Ferment Filtrate is primarily a water based ferment rich in small peptides, amino acids and sugars with virtually no heavy oils or waxes. Because these molecules dissolve easily in water and do not linger on the pore lining the likelihood of them clogging pores is very low, earning the ingredient a rating of 1. It is generally suitable for skin prone to acne or breakouts. As with any single raw material the overall comedogenic risk of a finished product depends on the full formula and how the ingredient is combined with emulsifiers, oils and silicones.
Summary
Bacillus/Chrysanthemum Zawadskii Extract Ferment Filtrate is a fermented flower extract used mainly as a skin conditioner. The fermentation process breaks down chrysanthemum compounds into smaller molecules that attract water, calm irritation and support the skin barrier so formulas featuring the filtrate leave skin feeling soft, hydrated and comfortable.
While loved inside K-beauty style toners, masks and calming creams it is still a niche active in Western products so you may not find it on every shelf yet. Safety data and user experience show it to be gentle for most skin types with very low comedogenic risk and few reported adverse reactions. Even with such a mild profile it is smart to patch test any new product that lists this ferment to confirm your own skin agrees with it.
