Saccharomyces/Barley Seed Ferment Filtrate

Saccharomyces/Barley Seed Ferment Filtrate is a liquid extract produced by fermenting barley seeds with Saccharomyces yeast. During fermentation, the yeast breaks down barley components into smaller molecular compounds, which are then filtered to create a clear liquid ingredient. This fermentation process is believed to enhance the bioavailability of beneficial compounds present in the barley.In skincare formulations, this ingredient functions as a humectant—a substance that draws moisture from the environment and deeper skin layers to the surface, helping to improve skin hydration and main…

As a humectant, this fermented barley filtrate works by drawing moisture into the outer layers of the skin. Its molecular structure allows it to bind water molecules and hold them in place, preventing transepidermal water loss—the evaporation of water from the skin's surface.The fermentation process may also yield compounds with antioxidant properties, though the extent of these benefits in finished skincare products depends on concentration and formulation stability.

This ingredient is typically found in serums, toners, essences, and hydrating creams at low concentrations (generally under 1%). Apply to clean skin before heavier moisturisers to maximise its hydrating effect. It works well in layered skincare routines and can be used daily. If your skin is very sensitive or reactive, introduce it gradually to monitor tolerance.

Generally well-tolerated by most skin types. As with any fermented ingredient, those with sensitivities to yeast or fermentation byproducts should perform a patch test first.
