Ingredient review
Fermented Rice & Green Tea Complex
INCI: LACTOBACILLUS/RICE/CAMELLIA SINENSIS LEAF/TARAXACUM PLATYCARPUM FERMENT EXTRACT
A gentle fermented blend that supports skin radiance and barrier health without harsh irritation.
In plain English
This ingredient is made by fermenting rice, green tea leaves, and dandelion with friendly bacteria (Lactobacillus). Fermentation breaks down large molecules into smaller ones that skin can absorb more easily. The result is a mix of antioxidants from green tea, soothing compounds from dandelion, and gentle exfoliating acids from the fermentation process. It helps brighten skin, calm redness, and improve texture over time.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A fermented botanical extract created by culturing Lactobacillus bacteria with rice, green tea leaves, and dandelion. The fermentation process produces beneficial byproducts like amino acids, peptides, and mild organic acids.
How it works
The fermentation breaks down plant compounds into smaller, more bioavailable molecules. The resulting extract provides antioxidants (from green tea) that neutralize free radicals, mild exfoliation from natural acids that loosen dead skin cells, and soothing properties from dandelion that help calm irritation. It also supports the skin's microbiome by providing prebiotic-like compounds.
Pros
Gentle exfoliation
The fermentation produces mild acids that loosen dead skin cells, helping to smooth texture and improve radiance without the sting of stronger exfoliants.
Antioxidant boost
Green tea in the blend provides catechins that protect skin from environmental damage, which can help prevent premature aging.
Cons and cautions
Variable potency
The final concentration of active compounds depends on the fermentation process, so results can vary between products.
Potential for mild irritation
Some people with extremely sensitive skin may experience slight tingling or redness, especially if the product contains a high percentage of the ferment.
Best for
- Anyone looking for a gentle way to brighten and smooth skin
- People with dry or sensitive skin who want mild exfoliation without irritation
Use caution if
- Those with a known allergy to any of the source plants (rice, green tea, dandelion)
Usage tips
Safety summary
This ingredient is considered safe for topical use. The fermentation process is controlled to prevent contamination. Mild irritation is possible in very sensitive individuals, but it is generally well-tolerated.
Research notes
Studies on fermented plant extracts show they can improve skin hydration, barrier function, and antioxidant capacity. Specific research on this exact blend is limited, but the individual components (rice, green tea, dandelion) have been studied for their skin benefits.
