INCI: HANSENULA/KLOECKERA/LACTOBACILLUS/LACTOCOCCUS/LEUCONOSTOC/PEDIOCOCCUS/SACCHAROMYCES/FIG/LEMON FERMENT
A gentle, fermented blend that helps exfoliate and nourish skin without harsh chemicals.
In plain English
This ingredient is a mix of fig and lemon that has been fermented with several types of good bacteria and yeast. Fermentation breaks down the fruit into smaller, more skin-friendly molecules, which can help gently remove dead skin cells and support a healthy skin barrier. Think of it like a mild, natural exfoliant that also feeds your skin's microbiome.

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 complex created by combining fig and lemon with a cocktail of probiotic microorganisms including Hansenula, Kloeckera, Lactobacillus, Lactococcus, Leuconostoc, Pediococcus, and Saccharomyces. The fermentation process produces natural acids and enzymes that benefit the skin.
How it works
During fermentation, the microorganisms break down the fruit sugars and fibers into lactic acid, enzymes, and other bioactive compounds. When applied to skin, these compounds gently dissolve the bonds between dead skin cells, promoting a smoother texture. They also help maintain a balanced skin microbiome and support the skin's natural moisture barrier.
Pros
Gentle exfoliation
Provides mild exfoliation that is less irritating than many single-acid exfoliants, making it suitable for regular use.
Microbiome-friendly
The probiotic strains may help maintain a balanced skin microbiome, which is linked to healthier, more resilient skin.
Cons and cautions
Scent may be off-putting
Fermented ingredients often have a tangy or sour smell that some users find unpleasant, though it usually fades after application.
Not for severe sensitivity
Even though it's gentle, the active enzymes and acids can cause temporary tingling or redness in very reactive skin.
Best for
- People with dull or uneven skin texture
- Those looking for a gentle alternative to stronger chemical exfoliants
Use caution if
- Individuals with known allergies to figs or lemons
- Those with severely compromised skin barriers (e.g., active eczema or burns)
Usage tips
Safety summary
