1. Technical Principle

• Biocomposite Synergistic Technology: Adopts advanced medical-grade copolymerization compounding technology to organically combine biodegradable PDLLA polylactic acid and high-activity hyaluronic acid in a scientific proportion, integrating structural support and biological repair functions into one composite biomaterial.
• Bionic Scaffold Regeneration Mechanism: PDLLA forms a stable three-dimensional porous micro-scaffold in the dermis, providing long-term mechanical support for soft tissues and effectively resisting skin sagging and depression. Compounded HA fills the scaffold gaps to build a bionic extracellular microenvironment that fits human skin tissue.
• Controllable Degradation & Efficacy Transition: The composite system achieves synchronized degradation and tissue regeneration. The material degrades slowly and evenly in human tissue, gradually converting exogenous filling support into endogenous collagen proliferation, realizing seamless transition from instant shaping to long-term skin rejuvenation.

2. Technical Parameters

• Raw Material Purity: Both PDLLA and HA reach medical implant grade, with comprehensive purity ≥99%
• Microstructure: Uniform porous cross-linked structure, stable molecular arrangement, good ductility and toughness
• Degradation Cycle: Complete controllable biodegradation within 12–24 months, matching skin metabolism cycle
• Biocompatibility: Ultra-low immunogenicity, non-toxic, non-inflammatory, no tissue rejection
• Efficacy Durability: Long-lasting shaping and rejuvenation effect with stable structural support performance
• Storage Stability: Maintains complete biological and structural activity under conventional sealed storage conditions

3. Product Features

• Dual-functional Composite Advantage: Combines PDLLA’s high-strength shaping support and HA’s moisturizing and repairing properties, solving the single-function limitation of traditional filling materials, with both mechanical stability and biological activity.
• High Medical-grade Safety: Fully biodegradable composite material with no residual harmful metabolites after degradation. It is highly compatible with human dermal tissue, free from allergy, irritation and immune rejection risks.
• Natural & Non-stiff Shaping: Possesses moderate hardness and flexible tissue affinity, fits facial muscle movement naturally after implantation, avoiding stiff facial expressions and realizing ultra-natural aesthetic shaping effect.
• Strong Structural Stability: Excellent anti-displacement and anti-deformation capabilities, stable in dermal tissue for a long time, not easy to shift or collapse, ensuring lasting and uniform shaping effect.

4. Application Scenarios

• Precise Facial Contour Shaping: Suitable for temple filling, cheek augmentation, chin contour optimization and facial symmetry adjustment, creating delicate, three-dimensional and natural facial features.
• Deep Wrinkle Improvement: Effectively improves nasolabial folds, marionette lines, forehead lines and other deep wrinkles, smoothing skin texture and restoring flat and delicate skin.
• Comprehensive Facial Anti-Aging: Applied to improve overall facial sagging and dermal thinning, enhance dermal density and skin elasticity, and achieve full-face anti-aging and rejuvenation effects.
• Medical Aesthetic Soft Tissue Repair: Used for postoperative subtle soft tissue defect repair and depression reconstruction, adapting to professional medical aesthetic shaping and clinical skin tissue rehabilitation scenarios.
