General Information

Product Name: PDLLA Microspheres
CAS: 26023-30-3
Catalog: CI-MIC-007
Applications: Dermal fillers, regenerative medicine and soft tissue augmentation

PDLLA (Poly-D,L-lactic acid) microspheres, with a controlled particle size of 20-50 μm or 40-60 μm, exhibit faster degradation rates than PLLA, allowing for quicker clinical results. Fully biocompatible and biodegradable, PDLLA microspheres stimulate natural collagen regeneration, making them highly effective in long-lasting dermal filler formulations used in aesthetic medicine.

As a professional supplier of cosmetic and medical aesthetic raw materials, Alfa Chemistry offers premium PDLLA microspheres designed for advanced skin rejuvenation and volumizing applications.
