What Is Botrytis Cinerea Ferment Lysate Filtrate?

Botrytis Cinerea Ferment Lysate Filtrate is a fermented extract derived from Botrytis cinerea, a fungus commonly known as noble rot. The ingredient is created through fermentation and filtration processes that break down fungal cells, yielding a liquid concentrate rich in bioactive compounds and polysaccharides.

In skincare formulations, this ingredient functions primarily as an emollient, helping to soften and smooth the skin surface. Fermented ingredients are thought to contain metabolites produced during the fermentation process that may offer additional skincare benefits beyond basic moisturisation.

How It Works

Fermented ingredients work through two mechanisms. First, the physical emollient action coats the skin, reducing transepidermal water loss and creating a smoother surface. Second, the fermentation process generates bioactive compounds—such as amino acids, organic acids, and polysaccharides—that can penetrate the skin and support barrier function or provide antioxidant activity.

The lysate and filtrate are prepared by breaking down the fungal cells and filtering the resulting liquid, concentrating the beneficial compounds while removing cellular debris.

Clinical Evidence & References

Research specifically examining Botrytis Cinerea Ferment Lysate Filtrate in skincare is limited. Most evidence for fermented ingredients in general suggests they can improve skin hydration and support barrier health, though individual ferments may vary in their properties.

The emollient function is well-established for similar ingredients. More targeted clinical studies would be needed to define specific benefits or optimal concentration ranges for this particular fermented extract.

How to Use

This ingredient is typically incorporated into moisturisers, serums, and hydrating masks. As an emollient, it works well when layered into a routine with other hydrating or active ingredients. Apply to damp skin to enhance its hydrating effect, or use it as part of your regular moisturising step once or twice daily depending on your skin's needs and the formulation.

Safety & Precautions

Generally well-tolerated in skincare products. Those with sensitivity to fungal-derived ingredients should patch-test first, though allergic reactions are uncommon.
