Science
Mechanism of Action
This extract operates through multiple pathways: it inhibits melanin production and tyrosinase activity for a brighter, more even skin tone. Its potent antioxidant effects, largely attributed to polyphenols, efficiently neutralize free radicals. It actively stimulates collagen synthesis, which significantly improves skin firmness, elasticity, and overall texture. Essential vitamins, including B3 (niacin), fortify the skin's barrier function, while vitamin D aids in skin cell growth and repair. Additionally, it exhibits anti-inflammatory properties and enhances skin's moisturizing capabilities. For wound healing, it promotes neovascularization, epithelialization, and robust collagen synthesis. Furthermore, it demonstrates anti-tyrosinase, anti-elastase, anti-hyaluronidase, and anti-collagenase activities, contributing substantially to its anti-aging benefits.

Stability
The stability of β-glucans, a crucial active component, is highly pH-dependent; acidic conditions (pH 3-5) promote hydrogen bonding, increasing their rigidity and stability. Conversely, alkaline conditions (pH > 8) disrupt these bonds, leading to solubilization. β-glucans form thermally stable hydrogels above 60 °C, however, excessive heat exceeding 90 °C may cause degradation of chitin.
Safety
Safety Profile
Cosmetic compositions containing Pleurotus ostreatus extract up to 10 wt.% have been assessed as safe and are generally well-tolerated by the skin, exhibiting low potential for irritation or adverse reactions.
