What Is Bacillus/Zizania Latifolia Leaf Ferment Extract?
Bacillus/Zizania Latifolia Leaf Ferment Extract is obtained by fermenting the leaves of Zizania latifolia, a type of wild rice, with Bacillus bacteria. During fermentation the bacteria break down leaf compounds into smaller molecules, creating a fluid rich in amino acids, simple sugars, organic acids and antioxidants. These components help the finished extract bind water and comfort skin.
Zizania latifolia has been eaten for centuries across East Asia, and its leaves have long been used in folk beauty rinses. Modern cosmetic labs began experimenting with the plant to capture its antioxidant potential. Fermentation gained popularity because it makes plant actives more skin friendly and increases their availability. Today manufacturers steep fresh leaves in a controlled tank, introduce a selected Bacillus strain, keep the mix at an optimal temperature then filter and purify the resulting liquid.
You will most often see Bacillus/Zizania Latifolia Leaf Ferment Extract in lightweight moisturizers, hydrating toners, soothing sheet masks, anti-aging serums and after-sun gels. Formulators prize it for adding a natural water binding boost without a heavy or greasy feel.
Bacillus/Zizania Latifolia Leaf Ferment Extract’s Cosmetic Benefits/Uses
This ferment brings two main functions to skincare formulas
- Humectant – attracts and holds water on the skin surface, delivering immediate hydration, improving softness and helping other moisturizing ingredients perform better
- Skin conditioning – smooths the skin’s texture, supports a healthy barrier and leaves a supple, refreshed finish that can enhance the overall feel of the product
Who Can Use Bacillus/Zizania Latifolia Leaf Ferment Extract
This ferment is gentle and water based so it usually works for every skin type, from dry or mature skin needing extra moisture to oily or breakout-prone complexions that shy away from heavy creams. Its lightweight texture and non-greasy finish also make it friendly for combination and sensitive skin. There are no specific skin types that must avoid it unless an individual has a known allergy to rice plants or fermented botanical ingredients.
The extract is created by fermenting plant leaves with a microorganism that is not sourced from animals, so formulas using it are generally considered vegan and vegetarian. As always, check the entire ingredient list to confirm no other animal-derived materials appear in the final product.
There is no evidence that Bacillus/Zizania Latifolia Leaf Ferment Extract poses a risk during pregnancy or while breastfeeding. That said, this information is not medical advice and anyone who is pregnant or nursing should run any skincare product they plan to use past a qualified doctor just to be safe.
The ingredient does not make skin more sensitive to sunlight and can be used morning or night without increasing the need for extra sun protection beyond your normal daytime sunscreen.
Potential Side Effects/Adverse Reactions

If any unwanted reaction occurs stop using the product and consult a healthcare professional or dermatologist for guidance.
Comedogenic Rating
Rating: 0 / 5
Bacillus/Zizania Latifolia Leaf Ferment Extract is water based, contains no heavy oils or waxes and is used in very light concentrations, so it does not clog pores. Fermentation breaks the plant compounds into even smaller, more skin-compatible molecules that rinse away easily and leave no residue.
Because of this near-zero occlusive effect, the extract is considered suitable for acne-prone or breakout-prone skin.
As with any fermented material, purity and formulation quality matter. If the final product layers the ferment with greasy emollients the overall formula, not the ferment, could raise the pore-clogging potential.
Summary
Bacillus/Zizania Latifolia Leaf Ferment Extract acts mainly as a humectant and skin-conditioning agent. Its mix of amino acids, small sugars and organic acids pulls moisture into the upper layers of skin then helps smooth and soften the surface.
While it is not yet as famous as hyaluronic acid or glycerin, the ingredient is gaining traction in hydrating toners, lightweight gels and calming sheet masks thanks to its natural origin and gentle feel.
Current data shows it is safe for most users with a very low risk of irritation or clogged pores. Still, every formula is unique so do a quick patch test whenever you try a new product that features this or any other novel ferment.
