Abstract:
Poly-L-lactic acid (PLLA) is a synthetic biologic polymer that is suspended in solution and can be injected for soft-tissue augmentation. The most common adverse events generally are transient in nature, such as swelling, tenderness, pain, bruising, and bleeding. Persistent adverse events of PLLA primarily are papule and nodule formation. Injecting PLLA into the anterior neck is an off-label procedure and may cause a higher incidence of nodule formation.
