What Is Aspergillus … Extract?

This ingredient is a fermented extract derived from three sources: Aspergillus and Saccharomyces fungi, mulberry fruit (Morus alba), and rice ferment lees (the sediment left after rice fermentation). The combination is created through a fermentation process, which breaks down the plant and fungal components into smaller, more bioavailable molecules.

In skincare, it functions primarily as a humectant and skin conditioner, helping to draw moisture into the skin and improve its texture and suppleness. The fermentation process may also generate beneficial compounds such as amino acids and polysaccharides that support skin hydration and barrier health.

How It Works

As a humectant, this fermented extract works by attracting water molecules from the environment and deeper skin layers, binding them to the outer layers of the skin. This plumps the stratum corneum (the outermost layer) and can temporarily improve skin smoothness and hydration levels.

The fermentation process creates amino acids and polysaccharides, which are natural moisturising factors that mimic compounds found in healthy skin. These molecules help condition the skin surface and may support the skin barrier's natural protective function.

Clinical Evidence & References

Published clinical research specifically on this multi-component fermented extract is limited. However, fermented ingredients in general have been studied for their humectant and skin-conditioning properties, and individual components such as rice ferment extract have shown promise in supporting skin hydration and barrier function in some studies.

The ingredient is considered generally safe and well-tolerated in cosmetic formulations, though individual tolerance varies. More targeted research on this specific blend would help clarify its precise efficacy and optimal concentration ranges.

How to Use

This ingredient works well in serums, essences, and hydrating toners where its humectant properties can be most effective. For best results, apply to damp skin to maximise moisture absorption. It can be layered with other hydrating or treatment products and used both morning and evening as part of a regular skincare routine.

Safety & Precautions

Generally well-tolerated and suitable for most skin types. Fermented ingredients are unlikely to cause irritation, though those with sensitivities to fermented foods should patch test first.
