Biocompatible PDLLA Filler Poly-DL-Lactide Anti Wrinkle Facial Rejuvenation

1. Technical Principle

• 3D Bionic Support Shaping: PDLLA adopts high-purity bionic polylactide polymer structure. After subcutaneous application, it forms a stable three-dimensional stereo support framework, which can instantly fill facial concave defects, prop up loose collapsed tissues, and effectively lift sagging skin to refine blurred facial contours.
• Fibroblast Endogenous Activation: The unique ordered molecular chain structure of PDLLA can continuously activate dermal fibroblast activity, stimulate the proliferation and synthesis of autologous collagen and elastic fibers, and fundamentally improve skin elasticity loss caused by aging.
• Skin Collagen Network Reconstruction: It induces the ordered regeneration and rearrangement of new collagen fibers, repairs the collapsed and loose dermal support structure, rebuilds a complete, tight and elastic skin three-dimensional network, and restores skin basal vitality.
• Controllable Slow Degradation Replacement: PDLLA features uniform slow degradation performance in human tissues. The degraded harmless small molecules will be metabolized naturally, and the newly grown autologous collagen gradually replaces the polymer support, realizing natural and non-rigid long-term anti-aging effect.
• Subcutaneous Microenvironment Optimization: The degradation products can improve subcutaneous microcirculation, relieve skin aging fatigue, uniform skin tone, reduce dullness, and comprehensively enhance skin transparency and delicate texture.

2. Production Process

• Medical-Grade Raw Material Screening: Select high-standard medical aesthetic grade PDLLA raw materials, strictly screen molecular weight, purity and monomer residue indicators, eliminate impure and deteriorated raw materials to ensure consistent batch quality foundation.
• Low-Temperature Bionic Polymerization: Adopt low-temperature constant-pressure polymerization synthesis technology to optimize macromolecular chain arrangement, improve tissue affinity and biological activity, and avoid high-temperature induced molecular inactivation and performance decline.
• Multi-Stage Precision Purification: Go through multi-layer ultrafiltration and membrane filtration purification processes to remove macromolecular aggregates, residual monomers and microscopic impurities, reaching high-purity medical-grade standard without harmful components.
• Molecular Slow-Release Stabilization: Implement professional molecular modification and stabilization treatment, balance degradation cycle and active release efficiency, ensure stable and continuous collagen induction ability, and avoid premature efficacy attenuation.
• Aseptic Dust-Free Filling & Testing: Complete all production operations in Class 100 dust-free sterile workshop, conduct secondary sterile filtration and sealed filling, with strict batch sampling inspection to ensure sterile, safe and stable finished products.

3. Product Advantages

• Dual Shaping & Regeneration Mechanism: Different from single physical filling materials, it integrates instant contour shaping and long-term endogenous collagen regeneration, realizing dual anti-aging effects of external modification and internal skin rejuvenation.
• Ultra-Long Lasting Efficacy: Relying on controllable slow degradation and slow-release activation technology, the anti-aging and shaping effect lasts longer than ordinary fillers and anti-aging raw materials, with stable efficacy and no rebound.
• High Biological Safety: Pure medical-grade polymer formula, low immunogenicity, non-toxic and non-irritating. It is highly compatible with human tissues without rejection reaction, residue accumulation and long-term hidden skin risks.
• Natural & Non-Stiff Shaping: After tissue integration and collagen regeneration, the facial texture is natural and real, without rigid artificial filling sense, which perfectly fits skin tissue movement and expression.
• Wide Formula Compatibility: Stable physical and chemical properties, compatible with various medical aesthetic filling formulas and high-end anti-aging skincare systems, easy to formulate and process, suitable for industrial mass production.
