Poly D,L-lactic Acid (PLLA) Microspheres

PDLLA racemic polylactic acid microspheres are a new generation of medical regenerative materials that combine high safety and regenerative function. They are non-toxic, non-irritating, and have excellent biocompatibility, completely degrading into carbon dioxide and water after entering the human body, leaving no residue or accumulation. Their medical aesthetic applications include facial rejuvenation injections and regenerative gel fillers. Compared to traditional solid PDLLA microspheres, porous PDLLA microspheres can guide the orderly deposition and directional growth of collagen fibers through their porous structure, continuously and directionally activating the regeneration of autologous collagen. This avoids problems such as uneven collagen accumulation and localized nodules, while achieving long-lasting anti-aging effects that closely resemble the natural state.
