Mechanism of Action
This ferment filtrate influences skin health through several synergistic pathways. It provides significant antioxidant protection, mitigating oxidative stress and contributing to a more luminous complexion. Its anti-inflammatory properties are manifested through the inhibition of inflammatory mediators like nitric oxide (NO) and tumor necrosis factor-α (TNF-α), concurrent with stimulating IL-10 and suppressing IL-6, thereby calming irritation and reducing redness. Furthermore, it encourages skin regeneration by stimulating the formation of new cells, accelerating recovery from environmental damage, and refining skin texture. The ingredient also effectively targets hyperpigmentation by inhibiting melanin production and tyrosinase activity, leading to a reduction in melanogenesis-related proteins and a visible skin-lightening effect. Additionally, it enhances skin hydration and fortifies the skin's natural barrier functions.

Key findings
- 01 A 3% topical application of a mycelia culture broth, comprising eight traditional herbal extracts fermented with Phellinus linteus, achieved a 32.2% reduction in melanin pigmentation on UVB-induced hyperpigmented brown guinea pigs over 4 weeks, demonstrating a skin-lightening effect comparable to 2% arbutin.
- 02 In vitro studies at 100 μg/mL showed that Phellinus linteus polysaccharides significantly decreased TNF-α, stimulated IL-10, and suppressed IL-6 over 6 to 24 hours, confirming potent anti-inflammatory effects.

Stability
The ingredient's stability is optimally maintained within a pH range of 4.0 to 7.0, reflecting the conditions favorable for Phellinus linteus mycelial growth (typically pH 5.5-6.0 and 28-30°C). As a product of water-based extraction during fermentation, it exhibits excellent aqueous solubility.
Safety
Safety Profile
Phellinus Linteus Extract is generally regarded as having a favorable safety profile. While severe adverse reactions are rare, some individuals with specific sensitivities to fungal extracts may experience mild allergic responses such as localized itching or redness; a preliminary patch test is therefore recommended. While recognized as a safe cosmetic component in many countries, adherence to specific local regulations and manufacturer recommendations is advised.
