What Is Lactobacillus … Ferment?

This ingredient is a fermented complex that combines Lactobacillus (beneficial bacteria), rice bran, Saccharomyces (yeast), and Camellia sinensis (green tea) leaf extract. Fermentation breaks down plant compounds into smaller, potentially more bioavailable molecules whilst the microorganisms generate additional beneficial metabolites during the process.

The combination is designed to deliver antioxidant and skin-conditioning benefits. Rice bran contributes vitamins and minerals, whilst green tea is a recognised source of polyphenols. The fermentation process may enhance the stability and efficacy of these components.

Benefits for Your Skin

How It Works

The fermentation process creates a synergistic blend: the Lactobacillus and Saccharomyces generate bioactive compounds whilst breaking down complex plant structures. This makes the antioxidants and nutrients from rice bran and green tea more readily absorbed by the skin.

Once applied, the polyphenols and conditioning agents work to protect against oxidative stress and support the skin barrier's natural moisture balance. The probiotic-derived compounds may also have a gentle regulating effect on skin microbiota.

Clinical Evidence & References

Green tea polyphenols are well-documented for antioxidant activity in skincare. Rice bran has a history of use in traditional skincare and contains compounds with conditioning properties. However, specific research on this multi-component fermented blend is limited.

Most evidence relates to the individual ingredients rather than the fermented complex as a whole. The fermentation process itself is thought to enhance bioavailability, though independent clinical studies validating this specific formulation are not widely published in peer-reviewed literature.

How to Use

This ingredient typically appears in serums, essences, and hydrating toners. It integrates well into layered skincare routines and can be applied to clean skin before moisturisers or oils. As with any new ingredient, introduce it gradually to monitor tolerance.

Safety & Precautions

Generally well-tolerated by most skin types. Those with confirmed sensitivities to fermented ingredients or any component should patch-test first.
