Science
Mechanism of Action
This ingredient primarily functions as an antioxidant, offering potential protection against oxidative damage. Components originating from the *Lepista nuda* mushroom demonstrate robust antioxidant capabilities, including the ability to chelate iron ions, thereby mitigating the formation of harmful free radicals. Furthermore, it exhibits efficacy in scavenging both DPPH and superoxide anion radicals.

Stability
While explicit data for the ferment filtrate powder's stability is not available, studies on the *Lepista nuda* mushroom indicate maximum biomass production in liquid culture at pH 7. Its natural habitats typically exhibit a soil pH range of 3.6 to 5.20, averaging 4.75, suggesting potential adaptability to varying pH conditions.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically evaluated Lepista Nuda Ferment Filtrate Powder. While general categories like 'Lactobacillus Ferment Ingredients' and 'Yeast-Derived Ingredients' have broad safety assessments (e.g., up to 5.6% in face products, 90.7% in moisturizers), these do not directly address this particular mushroom ferment. Therefore, specific maximum concentration limits and sensitization risks for this ingredient remain undetermined. Paula's Choice currently lists it as 'Not rated' with 'No known benefits'.
