What Is Aspergillus … Ferment Filtrate?

This ingredient is a fermented extract made from three components: Aspergillus and Saccharomyces (beneficial fermentation microorganisms) combined with Gastrodia Elata Root, a traditional plant extract. The fermentation process breaks down the plant material into smaller molecules that the skin may absorb more readily.

In skincare formulations, it functions primarily as a skin conditioner—meaning it helps improve the texture and feel of the skin surface whilst supporting hydration and suppleness.

How It Works

Fermentation breaks down complex plant compounds into smaller molecules and metabolites that can penetrate the outer skin layers more effectively than the raw plant material. These smaller molecules can then work to condition the skin and support hydration at a cellular level.

The specific mechanisms are not extensively documented in published research, so the precise way this particular blend functions remains partially understood. Its role is primarily supportive rather than transformative.

Clinical Evidence & References

Published clinical studies on this specific fermented blend are limited. Most evidence comes from cosmetic ingredient suppliers and brand-sponsored research rather than independent peer-reviewed studies.

Fermented plant extracts in general have shown promise in skincare for hydration and antioxidant benefits, but claims about this ingredient should be treated cautiously without stronger independent validation. It appears to be well-tolerated in cosmetic use.

How to Use

This ingredient is typically used as part of a complete formulation rather than in isolation. It works well in serums, essences, and hydrating creams. Since it's a conditioning agent, consistent daily use will yield better results than occasional application. Combine with a good moisturiser to maximise hydration benefits.

Safety & Precautions

Generally well-tolerated in skincare products. Fermented ingredients are unlikely to cause irritation, though those with sensitivities to fermented foods or moulds should patch test first.
