Lactobacillus/Soybean Extract Ferment Filtrate

Lactobacillus/Soybean Extract Ferment Filtrate is a fermented ingredient derived from soybean extract using beneficial lactobacillus bacteria. The fermentation process breaks down soybean compounds into smaller, more bioavailable molecules that can be more readily absorbed by the skin.In skincare formulations, this ingredient functions primarily as a skin conditioner. It is typically included to support the skin's hydration status and overall condition, rather than to target a single specific concern.

Fermentation using lactobacillus bacteria creates peptides, amino acids, and other bioactive compounds that are smaller and more readily absorbed than the original soybean proteins. These components can interact with the skin's outer layers to improve hydration and condition.The filtrate (liquid portion) is used in formulations to ensure a stable, easy-to-incorporate ingredient. Because it is fermented rather than raw, it may also have a lower likelihood of triggering irritation in sensitive individuals.

This ingredient is typically found in serums, essences, toners, and creams. Because it functions as a conditioner rather than an active treatment, it can be used daily as part of a regular skincare routine. Layer it before heavier moisturisers to allow absorption, or use it as part of a multi-step routine suited to your skin's needs.

Generally well-tolerated across skin types, including sensitive skin. Because it is fermented, it is unlikely to cause irritation, though those with soy sensitivities should avoid it.
