What Is Botrytis Ferment Extract Filtrate?

Botrytis ferment extract filtrate is derived from the controlled fermentation of Botrytis, a fungal organism. The fermentation process breaks down cellular material into smaller, bioavailable compounds that can be filtered and incorporated into skincare formulations.

This ingredient functions primarily as an antioxidant and skin conditioner, helping to protect skin from environmental stressors and maintain hydration and suppleness.

Benefits for Your Skin

How It Works

As a fermented extract, this ingredient contains bioactive compounds produced during the fermentation process. These compounds can penetrate the skin more easily than their larger, unfermented precursors, allowing them to work at a cellular level.

The antioxidant compounds neutralise free radicals, which are unstable molecules that can damage skin cells and accelerate visible signs of ageing. Simultaneously, the conditioning properties help maintain skin hydration and barrier function.

Clinical Evidence & References

Research specifically investigating Botrytis ferment extract filtrate in skincare is limited. The ingredient has been adopted by the cosmetics industry based on fermentation technology's general ability to enhance ingredient bioavailability and antioxidant potency.

Evidence for fermented ingredients more broadly suggests they can deliver beneficial compounds to skin, though individual studies on this particular ferment are not widely published in peer-reviewed literature. Formulations containing this ingredient may benefit from the inclusion of other clinically substantiated actives.

How to Use

This ingredient is typically found in serums, essences, and moisturisers. It can be used daily as part of your regular skincare routine. Apply to clean skin before heavier products, or incorporate into your existing moisturiser. No special preparation or sequencing is required unless combined with other active ingredients, in which case follow the product instructions.

Safety & Precautions

Generally well-tolerated in cosmetic formulations. As with any fermented ingredient, those with sensitivities to fermentation byproducts should patch test first.
