What Is Lactobacillus … Ferment Filtrate?

This ingredient is a fermented filtrate derived from broccoli extract, created through the fermentation process using Lactobacillus and Leuconostoc bacteria. Fermentation breaks down plant compounds into smaller, more bioavailable molecules that the skin can more readily absorb and utilise.

It functions primarily as a humectant and skin conditioner, helping to draw moisture into the skin and support the overall health of the skin barrier. The fermentation process produces beneficial compounds that may enhance the ingredient's skincare properties beyond what the raw broccoli extract alone would offer.

How It Works

As a humectant, this fermented ingredient draws water molecules from the environment and deeper skin layers into the outermost layer, improving hydration at the surface. The fermentation process creates smaller molecular compounds that can penetrate the skin more effectively than unfermented plant material.

The broccoli-derived components, including compounds like sulforaphane precursors, may also provide antioxidant and anti-inflammatory benefits that support overall skin health and resilience.

Clinical Evidence & References

Research specifically on this fermented broccoli filtrate in skincare is limited. However, fermented plant extracts in general have shown promise in cosmetic studies for improved skin hydration and barrier function compared to their non-fermented counterparts.

Broccoli extract itself contains bioactive compounds with established antioxidant properties. The fermentation process is thought to enhance bioavailability, though direct clinical evidence on skin outcomes for this specific ingredient remains sparse. More targeted studies would help clarify its efficacy in topical skincare formulations.

How to Use

This ingredient is typically found in hydrating serums, essences, and moisturisers. It works well alongside other humectants and hydrating ingredients. Use it as part of your regular skincare routine; there is no need for intermittent or pulse dosing, as it is gentle and suitable for daily application.

Safety & Precautions

Generally well-tolerated by most skin types. Those with sensitivity to fermented ingredients or broccoli-related plants may wish to patch test first, though reactions are uncommon.
