What Is Galactomyces/Phellinus Linteus Extract Ferment Filtrate?

Galactomyces/Phellinus Linteus Extract Ferment Filtrate is a fermented ingredient derived from two sources: Galactomyces (a yeast) and Phellinus Linteus (a medicinal fungus). During fermentation, these organisms break down their cellular components into smaller molecules, creating a filtrate rich in polysaccharides, amino acids, and other bioactive compounds.

In skincare, this ingredient functions as a humectant—meaning it draws moisture into the skin—and as a skin conditioning agent that may help support the skin's natural protective barrier.

Benefits for Your Skin

How It Works

Fermented extracts like this work through multiple mechanisms. The polysaccharides and amino acids act as humectants, binding water molecules and drawing them into the epidermis. This increases skin hydration and plumpness.

Additionally, fermentation creates smaller molecular fragments that may penetrate more easily and potentially stimulate the skin's own barrier-supporting processes. Some evidence suggests fermented ingredients can support skin microbiota balance, though research specific to this blend remains limited.

Clinical Evidence & References

Research on fermented yeast and fungal extracts suggests benefits for skin hydration and barrier function, though most studies examine individual components rather than this specific combination. Fermented ingredients generally show promise for improving skin moisture retention and reducing transepidermal water loss.

Evidence specific to Galactomyces/Phellinus Linteus blends in published clinical trials is limited. Existing data supports its use as a hydrating and conditioning agent, but claims about deeper anti-inflammatory or regenerative effects warrant cautious interpretation.

How to Use

This ingredient works well in serums, essences, and moisturisers and can be layered with most other actives. Apply to damp skin to maximise hydration benefits. It's generally well-tolerated enough for daily use, though those introducing it should observe their skin's response over a few weeks before incorporating it into a complex routine.

Safety & Precautions

Generally well-tolerated by most skin types. Those with fungal acne sensitivities should note that fermented ingredients may theoretically support certain fungal species; patch testing is advisable if concerned.
