PLEUROTUS CYSTIDIOSUS FERMENT FILTRATE.

Valuable / HUMECTANT

Pleurotus Cystidiosus Ferment Filtrate, derived from oyster mushroom fermentation, is a multifaceted skincare ingredient. It exhibits robust antioxidant and UV radiation-protective effects against photoaging, alongside significant potential for skin brightening, deep hydration, and soothing inflammatory responses.

Summary

Humectant Antioxidant Skin brightening UV protectant Anti-inflammatory Antimicrobial Anti-hyaluronidase

Science

Mechanism of Action

This ferment filtrate operates through several key pathways. It effectively neutralizes free radicals, demonstrating potent antioxidant activity crucial for mitigating cellular oxidative stress. Its rich composition of bioactive compounds, including polysaccharides, ergothioneine, and phenolics, contributes to anti-tyrosinase effects that support skin brightening. Furthermore, it offers in vitro UV radiation-protective effects against photoaging in human keratinocytes and functions as an effective humectant, attracting and binding moisture within the skin and cosmetic formulations.
