What Is Saccharomyces/Day Lily Flower Ferment Filtrate?

Saccharomyces/Day Lily Flower Ferment Filtrate is a fermented extract derived from day lily flowers using Saccharomyces (baker's yeast) as the fermentation culture. The fermentation process breaks down plant cell walls and creates a filtrate rich in small molecular compounds, amino acids, and other bioactive components that may be more easily absorbed by the skin.

In skincare, this ingredient functions primarily as a skin conditioner, helping to improve texture and maintain hydration. Fermented botanical extracts are valued in cosmetic formulation for their potential to deliver multiple beneficial compounds in a single ingredient.

How It Works

Fermentation breaks down the complex structure of plant cell walls, creating smaller molecules that can penetrate the outer layers of skin more readily than whole plant material. This process may also generate bioactive metabolites produced by the yeast itself, which can contribute to the overall conditioning benefit.

Once applied, the extract works to condition the skin surface by improving water-binding capacity and creating a more uniform texture. The amino acids and polysaccharides present in fermented extracts support the skin's natural moisturising factors.

Clinical Evidence & References

Published clinical research specifically evaluating Saccharomyces/Day Lily Flower Ferment Filtrate is limited. Most evidence for this ingredient comes from in vitro studies and manufacturer data rather than human clinical trials.

That said, fermentation as a processing method is well-regarded in cosmetic science for enhancing ingredient bioavailability and bioactivity. Individual components of fermented plant extracts—such as amino acids and polysaccharides—have shown hydrating and conditioning properties in broader research, though the specific efficacy of this particular filtrate would benefit from independent clinical validation.

How to Use

This ingredient is typically found in serums, essences, and hydrating toners. It works well in layered routines and can be used both morning and evening. Because it is a conditioning agent rather than an active treatment, it complements other skincare steps without competing for efficacy. Apply to clean skin before heavier creams or oils.

Safety & Precautions

Fermented botanical extracts are generally well-tolerated. Individuals with yeast sensitivities or a documented allergy to lilies should avoid this ingredient, though systemic reactions from topical use are rare.
