Science
Mechanism of Action
Functioning as a multi-faceted skin agent, this ferment filtrate provides antioxidant protection by scavenging free radicals and mitigating oxidative stress. Its anti-photoaging efficacy is attributed to inhibiting matrix metalloproteinase-1 (MMP-1), an enzyme responsible for collagen degradation, and reducing senescence-associated β-galactosidase levels in UVA-exposed skin cells. Furthermore, it acts as a humectant and skin conditioning agent. Components from Citrus unshiu peel are known to inhibit tyrosinase, suggesting a role in reducing melanin production, while Schizophyllum commune also contributes to melanin inhibition and possesses anti-inflammatory benefits.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically evaluated 'SCHIZOPHYLLUM COMMUNE/CITRUS UNSHIU PEEL EXTRACT FERMENT FILTRATE'. However, 'Citrus Unshiu Fruit Extract', a related component, has been deemed safe by CIR when formulated to be non-sensitizing and non-irritating, provided leave-on products contain no more than 0.0015% (15 ppm) 5-methoxypsoralen (5-MOP). For ferment filtrates derived from yeast, CIR has sometimes issued 'Insufficient Data Announcements' requesting further information. No SCCS or FDA review status was found for this specific ingredient.
