Science
Mechanism of Action
This extract operates through several biological pathways to enhance skin vitality. Its potent antioxidant capacity helps neutralize free radicals, mitigating cellular damage and promoting a radiant complexion. Anti-inflammatory effects are observed through the suppression of key pathways such as NF-κB and MAPK, leading to a reduction in inflammatory mediators like iNOS, NO, and TNF-α. This action effectively calms irritation, alleviates redness, and reduces dryness. Furthermore, it supports skin regeneration by encouraging new cell formation, which aids in post-damage recovery and refines skin texture. The ingredient also contributes to skin brightening by inhibiting both melanin synthesis and tyrosinase enzyme activity within melanocytes. Complementary benefits include enhanced hydration and improved skin barrier function.

Key findings
- 01 A 3% topical application of mycelial culture broth fermented with Phellinus linteus (8-HsPLCB) significantly reduced melanin index values and melanin pigmentation in the basal layer of the epidermis in brown guinea pigs with UVB-induced hyperpigmentation after 4 weeks. This skin-lightening effect was comparable to that observed with 2% arbutin.

Stability
Optimal pH values cited in the literature primarily relate to the conditions for mycelial growth and fermentation of Phellinus linteus, typically ranging from pH 5.2 to 7.0, rather than the stability of the final ferment extract within cosmetic formulations.
Safety
Safety Profile
While Phellinus Linteus Extract generally exhibits a favorable safety profile, a low potential for rare allergic reactions, such as skin itching or redness, has been noted in some users. This ingredient has not undergone a formal review by the Cosmetic Ingredient Review (CIR).
