Fermented Sugar Cane Extract
INCI: Lactobacillus/Sugar Cane Extract Ferment Filtrate
A gentle fermented extract that helps exfoliate and brighten skin without harsh chemicals.
In plain English
This ingredient is made by fermenting sugar cane with friendly bacteria (Lactobacillus). The fermentation process creates natural acids and enzymes that gently remove dead skin cells, helping your skin look smoother and more radiant. It's a milder alternative to stronger chemical exfoliants like glycolic acid.

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 filtrate derived from sugar cane (Saccharum officinarum) using Lactobacillus bacteria. The fermentation breaks down sugars into natural alpha hydroxy acids (AHAs), amino acids, and other bioactive compounds.
How it works
When applied to skin, the natural AHAs (mainly glycolic acid) from the fermentation process gently dissolve the bonds between dead skin cells, encouraging them to shed. This reveals fresher, brighter skin underneath and can improve texture over time. The fermentation also produces antioxidants and moisturizing compounds that support the skin barrier.
Pros
Gentle exfoliation
The fermentation process creates mild AHAs that exfoliate without the sting often associated with pure glycolic acid, making it suitable for sensitive skin types.
Brightening effect
Regular use can help fade dark spots and improve overall skin radiance by encouraging cell turnover.
Cons and cautions
Variable potency
Because it's a natural ferment, the exact concentration of active acids can vary between batches, leading to inconsistent results.
Mild tingling possible
Some users with very sensitive skin may still experience a slight tingling sensation, especially in higher-concentration products.
Best for
- People with dull or uneven skin tone looking for gentle exfoliation
- Those with sensitive skin who find traditional AHAs too harsh
Use caution if
- Anyone with active sunburn, open wounds, or severe skin conditions should avoid until healed
Usage tips
Safety summary
Generally recognized as safe for cosmetic use. The fermentation process reduces the potential for irritation compared to pure AHAs. Patch test recommended for first-time users.
Research notes
Studies on fermented plant extracts show they can provide mild exfoliation and antioxidant benefits. Direct clinical trials on this specific ingredient are limited, but the mechanism is well understood through AHA research.
