What Is Lactobacillus/Turmeric Ferment Filtrate?

Lactobacillus/Turmeric Ferment Filtrate is a liquid extract created by fermenting turmeric with beneficial Lactobacillus bacteria. The fermentation process breaks down turmeric's compounds into smaller molecules, which may enhance skin penetration and bioavailability compared to raw turmeric powder.

In skincare, this ingredient functions primarily as a humectant—meaning it draws water into the skin's outer layers. The fermentation byproducts may also offer antioxidant and skin-conditioning properties, though the extent depends on the fermentation method and post-processing.

How It Works

Humectants work by binding water molecules and drawing them into the outer layer of skin (the stratum corneum), which helps maintain hydration and skin plumpness. Lactobacillus fermentation produces organic acids and metabolites that may enhance this hydrating effect.

Turmeric's active compounds—particularly curcuminoids—have documented antioxidant properties. Fermentation may make these compounds more stable and bioavailable. The exact mechanism in skincare is not fully characterised, but the combination of hydration and antioxidant support is the likely basis for skin conditioning benefits.

Clinical Evidence & References

Direct clinical evidence specifically for Lactobacillus/Turmeric Ferment Filtrate in skincare is limited. Most research focuses on turmeric or Lactobacillus separately rather than this combined fermented extract.

Turmeric is well-documented for antioxidant and anti-inflammatory properties in scientific literature, and fermentation can enhance bioavailability of beneficial compounds. Lactobacillus ferments are increasingly used in skincare for their potential to support skin barrier function and tolerance. However, claims about this specific ingredient should be viewed as preliminary until more targeted studies are available.

How to Use

Apply to clean, damp skin as part of your toner or essence step, or use within a serum formulation. Ferment filtrates work well layered under heavier creams. If introducing this ingredient for the first time, use it a few times per week initially to assess tolerance, then increase frequency if well-tolerated. It pairs well with other hydrating and antioxidant ingredients.

Safety & Precautions

Generally well-tolerated, particularly because fermentation often reduces irritancy. Turmeric can cause sensitivity in some individuals, so patch test if you have known sensitivities to turmeric or fermented ingredients.
