PLLA (Poly L-Lactic Acid) Microspheres

Poly(L-lactic acid) (PLLA) microspheres are small spherical particles made from poly(L-lactic acid), a biodegradable and biocompatible polymer derived from lactic acid. PLLA represents a cutting-edge development in biodegradable materials. Its degradation product in the human body is L-lactic acid, a natural substance found in the body. L-lactic acid is further metabolized into carbon dioxide and water, which can be completely excreted from the body. Due to these characteristics, PLLA has been highly recognized in the medical community, making it one of the few biodegradable medical materials certified and approved by authoritative institutions in several countries and regions, including the European Union, the United States, and South Korea. These features further make PLLA microspheres ideal for a wide range of applications, particularly in medical and cosmetic fields. In cosmetic field, when PLLA microspheres penetrate into the deeper layers of the skin, these microspheres gradually release PLLA into the skin tissue, stimulating collagen production. This process helps to smooth out wrinkles and improve skin laxity, making it one of the most sought-after materials in the domestic medical aesthetics market today.
