What Is Saccharomyces … Filtrate?

This ingredient is a composite of three components: Saccharomyces (a yeast-derived ferment), Licorice Root Extract, and Rice Ferment Extract Filtrate. The combination creates a filtrate—a liquid extract—that brings together the antioxidant and skin-conditioning benefits of each element. Fermented ingredients are created through controlled microbial processes that can break down plant materials into smaller, potentially more bioavailable molecules.

The blend functions as an antioxidant and humectant, meaning it helps protect skin from free radical damage whilst also drawing moisture into the outer layers of the skin. It is commonly found in essences, serums, and hydrating treatments.

Benefits for Your Skin

How It Works

The fermented components in this blend are thought to work through multiple pathways. Fermentation can create compounds with enhanced antioxidant capacity, which may help neutralise reactive oxygen species (ROS) that contribute to skin ageing and inflammation. The licorice root component contains flavonoids and other polyphenols known for antioxidant and anti-inflammatory activity.

As a humectant, the filtrate draws water molecules from the dermis into the epidermis, temporarily improving skin hydration and plumpness. The combination of these properties may also support the skin's natural defence mechanisms against environmental stressors.

Clinical Evidence & References

Evidence specific to this exact combination is limited. However, individual components have been studied: licorice root extract has demonstrated antioxidant and anti-inflammatory activity in several in vitro and animal studies, whilst rice ferment extracts are reported to contain polyphenols and amino acids with skin-conditioning properties. Fermented ingredients generally show promise as a delivery method for bioactive compounds, though human clinical data for this specific filtrate is sparse.

Most claims around this ingredient rest on the properties of its individual components rather than robust clinical trials of the blend itself. Further research would help clarify its efficacy in real-world skincare use.

How to Use

This ingredient is typically found in lightweight hydrating products such as essences and serums, which are best applied to damp skin to maximise its humectant effect. It generally sits well in layering routines and can be used morning and evening. As with any new product, introduce it gradually to monitor for any adverse reactions, particularly if you have reactive or sensitised skin.

Safety & Precautions

Generally well-tolerated in cosmetic formulations. Licorice root is considered safe for topical use, though rare sensitivity is possible. Avoid if you have a known allergy to any of the component plants.
