Science

Lentinus Edodes/Hydrolyzed Rice Bran Ferment Filtrate Extract exhibits a broad spectrum of beneficial actions on the skin. Functioning as a potent antioxidant, it neutralizes damaging oxygen species and free radicals, thereby preserving skin protein integrity and preventing a dull, aged appearance. Its anti-inflammatory properties are effective in reducing irritation and calming the skin, making it suitable for sensitive conditions. The ingredient also demonstrates antimicrobial activity, capable of inhibiting detrimental bacteria such as *P. acnes*, a contributor to acne development. As a comprehensive skin conditioning agent and humectant, it optimizes skin hydration, leading to a softer, smoother texture and improved overall appearance. Furthermore, it actively addresses aging concerns by promoting the synthesis of essential structural proteins like collagen and elastin, enhancing fibroblast migration, and improving the skin's mechanical resilience. It also targets hyperpigmentation through the inhibition of melanin synthesis and protects cellular health by reducing fibroblast senescence and MMP-1 expression.
