What Is Lactobacillus/Phaseolus Radiatus Seed Ferment Filtrate?

Lactobacillus/Phaseolus Radiatus Seed Ferment Filtrate is a bioactive ingredient derived from mung bean seeds (Phaseolus radiatus) that have been fermented using beneficial Lactobacillus bacteria. The fermentation process breaks down the seed's cell walls and creates a filtrate rich in peptides, amino acids, and other small molecules that can be absorbed by the skin.

This ingredient functions primarily as a skin conditioner, meaning it helps to soften, smooth, and maintain the skin's moisture balance and overall texture.

How It Works

Fermentation breaks down the complex proteins and polysaccharides in mung bean seeds into smaller, more bioavailable molecules. These include amino acids, peptides, and fermentation metabolites that can penetrate the outer layers of skin more readily than larger molecules.

Once applied, these components work to strengthen the skin's natural moisture-binding capacity and support the structural proteins that maintain skin texture and elasticity. The fermentation process also produces beneficial organic acids and enzymes that may gently support skin renewal.

Clinical Evidence & References

Research specifically examining this fermented ingredient is limited in published dermatological literature. However, both mung bean extracts and Lactobacillus fermentation have been studied individually and show promising profiles for skin conditioning and barrier support.

The ingredient is widely used in cosmetic formulations and is generally considered well-tolerated. If you have concerns about efficacy or suitability for your skin, it is worth monitoring your own skin's response over 4–6 weeks of consistent use.

How to Use

This ingredient is typically found in serums, toners, essences, and moisturisers. It pairs well with other hydrating and barrier-supporting ingredients. Use as directed on the product label; most formulations are suitable for daily use both morning and evening. For best results, apply to clean, slightly damp skin to maximise hydration absorption.

Safety & Precautions

Generally well-tolerated across most skin types. As with any fermented ingredient, those with severe sensitivity to fermented foods or probiotics should patch-test first.
