Fermented Fruit & Plant Complex
INCI: LACTOBACILLUS/PROPIONIBACTERIUM/LACTOSE/LEMON FRUIT/DATE FRUIT/FIG FRUIT/WALNUT NUT/SOYBEAN/ONION BULB/SOYBEAN SPROUT/CELERY BULB/COCONUT FRUIT/ARTICHOKE BUDS/MILLET SEED/PEA POD FERMENT FILTRATE
A rich ferment blend that may help balance skin bacteria and provide antioxidant protection, but its complexity makes it hard to pinpoint exact benefits.
In plain English
This ingredient is a fermented mixture of many plant foods and probiotics. Think of it like a kombucha for your skin — the fermentation process breaks down the ingredients into smaller, potentially more beneficial compounds. It's meant to support the good bacteria on your skin and deliver antioxidants from fruits, nuts, and vegetables.

Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Fermented Fruit & Plant Complex.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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 ferment filtrate created by fermenting lactose and a diverse mix of plant materials (lemon, date, fig, walnut, soybean, onion, coconut, artichoke, millet, pea pod) with Lactobacillus and Propionibacterium bacteria. The resulting liquid is filtered to remove solids, leaving a complex blend of peptides, organic acids, vitamins, and antioxidants.
How it works
The fermentation process generates small molecules that can more easily penetrate the skin's surface. These compounds may help feed beneficial skin bacteria, support the skin's natural barrier, and provide antioxidant activity to neutralize free radicals. The organic acids produced during fermentation can also gently exfoliate and improve skin texture.
Pros
Microbiome-friendly
The ferment may provide prebiotic compounds that feed beneficial skin bacteria, helping maintain a balanced skin ecosystem.
Antioxidant-rich blend
With ingredients like lemon, date, fig, and artichoke, the ferment delivers a variety of antioxidants that can help protect skin from environmental stress.
Cons and cautions
Allergen complexity
The long list of plant sources increases the chance of skin sensitivity or allergic reaction, especially for those with nut or fruit allergies.
Unclear individual contribution
Because it's a complex mixture, it's hard to know which components are most active or if the blend is more effective than simpler ferments.
Best for
- People looking to support their skin's natural microbiome
- Those who enjoy fermented skincare and want a multi-antioxidant boost
Use caution if
- Individuals with known allergies to any of the listed fruits, nuts, or grains (e.g., walnut, soybean, coconut)
Usage tips
Safety summary
This ferment blend is considered safe for topical use in cosmetics at typical concentrations. The main safety concern is the potential for allergic reactions due to the many plant sources. Individuals with nut or fruit allergies should exercise caution. No significant irritation or comedogenicity has been reported in general use.
Research notes
Research on multi-plant ferments in skincare is growing but limited. Studies on individual components (e.g., Lactobacillus ferments, fruit extracts) show antioxidant and microbiome-supporting benefits. However, no peer-reviewed studies specifically examine this exact blend. Evidence is largely extrapolated from similar fermented ingredients.
Common label clues
- Typical concentration
- 1–10% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used as intended. No specific restrictions beyond standard cosmetic ingredient regulations.
- Common uses
- Serums, Moisturizers, Essences, Masks
- Environmental note
- The ingredient uses a variety of plant-based raw materials, some of which (like coconut and soybean) have environmental considerations regarding water use and land impact. Fermentation is a relatively low-energy process compared to chemical synthesis.
Good to know
- Fermentation can reduce the potential irritancy of some raw plant extracts, making this blend generally gentle.
- The presence of lactose means this is not suitable for vegans or those with dairy sensitivities.
