Plla Injection Filler is poly-L-lactic acid, which is a degradable polymer material. It is characterized by non-toxic, non-irritating, biodegradable absorption, high strength, good plasticity, and easy processing and molding. It is decomposed by enzymes in the body. The final formation of carbon dioxide and water has good biocompatibility.
The degradation cycle is 2-12 months. During the production and preparation, other ingredients can be added for modification to change the degradation cycle and make its absorption slower.
The same is PLLA material, white freeze-dried powder, the particle size of each brand is different, most of the brand microspheres are about 50 microns in diameter. The injection level is between the dermis layer and the superficial layer of the SMAS fascia. PLLA is stable at this level. The capacity of the supplement and the superficial nutritional effect are maximized.
