Anti Aging THROBIO PDLLA Dermal Filler Raw Powder For Facial

• Product Description: Medical-grade PDLLA (Poly-DL-Lactic Acid) is a non-crystalline amorphous random copolymer regenerative dermal filler, specially formulated for delicate facial anti-aging and soft tissue contouring. Different from high-crystallinity PLLA, PDLLA adopts disordered molecular structure with softer texture and superior tissue affinity. It integrates mild instant filling and continuous endogenous collagen regeneration, delivering progressive, natural and non-rigid rejuvenation effects. It effectively improves facial hollowing, soft tissue atrophy, medium and fine wrinkles, as well as skin laxity. With uniform degradation performance and high biosafety, it supports full-face delicate volume restoration and long-term skin condition optimization, perfectly fitting natural aesthetic demands.
• Product Features: PDLLA features a unique amorphous non-crystalline structure, eliminating crystal hardening and uneven degradation problems of traditional crystalline polylactic acid. It presents soft and smooth filling texture with excellent subcutaneous fusion, ensuring natural facial muscle movement without stiff expression. With medical-grade ultra-high purity, it achieves extremely low inflammatory response and zero granuloma risk after injection. It maintains stable volume support throughout the degradation cycle without sudden shrinkage or collapse. It dual balances physical contour shaping and biological collagen regeneration, effectively thickening dermal layers, improving skin texture and enhancing skin elasticity for long-lasting natural anti-aging results.
• Technical Principle: PDLLA is synthesized via random copolymerization of D-lactic acid and L-lactic acid monomers, forming a stable disordered amorphous molecular chain structure. This structural feature removes crystal stress defects and realizes uniform hydrolysis in human physiological environment. After subcutaneous injection, PDLLA provides immediate soft volume filling to repair facial depressions and wrinkles. The polymer ester bonds undergo slow, mild and steady hydrolysis, gradually decomposing into natural lactic acid, which is further metabolized into carbon dioxide and water with zero toxic residues. During the degradation process, PDLLA continuously activates dermal fibroblast activity, promotes autologous collagen proliferation and tissue remodeling, realizing organic combination of physical shaping and biological skin self-repair.
• Production Process: Medical-grade PDLLA adopts strict medical-level copolymerization synthesis and multi-stage deep purification technology, produced entirely in Class 100 dust-free sterile constant-temperature workshops. High-purity DL-lactic acid raw materials are screened and refined to remove moisture, micro-impurities and invalid monomers. Precise constant-temperature catalytic ring-opening copolymerization is applied to synthesize amorphous PDLLA polymers with uniform molecular weight distribution. Multiple devolatilization, catalyst removal and ultrafiltration purification processes thoroughly eliminate residual impurities. After sterile homogenization, precise blending and vacuum sealing packaging, the finished products achieve ultra-low sensitization, stable batch consistency and smooth injection performance for clinical aesthetic application.
