How PLLA Microspheres Work

Unlike traditional fillers that mainly add immediate volume, PLLA (Poly-L-Lactic Acid) microspheres work by stimulating the body's natural collagen production. After injection, the carrier solution is absorbed while the microspheres remain in the tissue, encouraging fibroblast activity and supporting the gradual formation of Type I collagen. This regenerative process helps improve skin firmness, elasticity, and facial volume over time, delivering natural-looking rejuvenation rather than an instant filling effect. At Reborn PLLA, we offer 150mg, 240mg, 360mg, 500mg, and 800mg specifications, allowing healthcare professionals to select the most appropriate dosage for different facial and body indications. As demand for collagen biostimulators continues to grow, PLLA has become an important solution in regenerative aesthetics. Understanding how PLLA microspheres work helps practitioners deliver personalized treatment strategies focused on long-term skin quality and natural collagen regeneration.
