What Is Lactobacillus … Filtrate?

This ingredient is a filtrate derived from fermenting turmeric with beneficial microorganisms—specifically Lactobacillus and Saccharomyces species. Fermentation breaks down plant compounds into smaller, potentially more bioavailable molecules, whilst the microorganisms themselves contribute metabolites with antioxidant properties.

The resulting extract combines turmeric's natural antioxidants (primarily curcuminoids) with fermentation byproducts, creating a multi-functional ingredient that addresses oxidative stress in the skin.

Benefits for Your Skin

How It Works

Antioxidants in this fermented extract work by donating electrons to free radicals, stabilising them and preventing them from damaging skin cells and collagen. Curcuminoids from turmeric are the primary active compounds, whilst fermentation-derived metabolites (such as polysaccharides) may enhance skin barrier function and hydration.

The fermentation process also creates shorter-chain molecules that penetrate more readily into the epidermis, potentially increasing efficacy compared to unfermented turmeric extract.

Clinical Evidence & References

Direct clinical studies on this specific fermented blend are limited. However, turmeric and curcumin have extensive research supporting antioxidant and anti-inflammatory effects in skin, with studies showing benefits for sensitivity, redness, and skin tone evenness.

Fermented botanical extracts broadly show promise for improved skin barrier function and antioxidant delivery, though the magnitude of benefit often depends on concentration and formulation context. More targeted research on this particular ingredient combination would strengthen confidence in specific claims.

How to Use

This ingredient is typically found in serums, essences, and lightweight moisturisers. Use twice daily as part of your routine, ideally after cleansing and before heavier creams. It pairs well with vitamin C or niacinamide for complementary antioxidant support, though patch testing is sensible if you have very reactive skin.

Safety & Precautions

Generally well-tolerated in cosmetic formulations. Turmeric can occasionally cause sensitivity in very reactive or compromised skin barriers, so introduce gradually if prone to irritation.
