1. Neutral pH and chemical stability: pH 6.8-7.8 (matches human physiological environment), avoiding tissue irritation from traditional highly alkaline glass (pH > 8). Nanoporous structure: pore rate 40%-70%, pore size 10-500nm (adjustable), specific surface area 50-300 m²/g, providing channels for cell adhesion and nutrient transmission. Ion-controlled release: Ca²⁺ (5-20mM), Si⁴⁺ (1-5mM), Na⁺ (10-30mM) and others (release rate regulated by component design). Biodegradability: degradation cycle 3-24 months (synchronized with bone regeneration/ tissue repair), degradation products involved in body metabolism (e.g., silicates →SugarAmine Synthesis.

2. Biological Characteristics - Bioactivity: Rapidly forms a hydroxyapatite (HA) layer on the surface (bionic mineralization, initiated within 12-24 hours), promoting cell adhesion (osteoblasts/fibroblasts). Neutral environment inhibits inflammatory factors (e.g., TNF-α, IL-6), protecting macrophage activity (phagocytic efficiency increased by 20%-30%). Synergistic Enhancement: Complexes with hyaluronic acid (HA) (hydrogen bonding) to enhance moisturizing power (water retention extended by 4 hours), and with plant extracts (Centella asiatica) (inhibits COX-2 by 75%). Tissue Compatibility: pH neutral value is stable, matches physiological environment, avoids irritation, maintains structural stability in aqueous phase (pH 5.5-7.0) and oil phase (petrolatum, silicone oil), and has better compatibility than traditional active ingredients (e.g., Vitamin C, Retinol).
