Poly-L-lactic acid (PLLA) is a biocompatible, re-absorbable, immunologically inert polymer that induces neocollagenesis through a subclinical inflammatory response. It is indicated for restoration of facial volume associated with facial lipoatrophy in immunocompetent or HIV-immunodeficient patients. In addition there are cosmetic indications for extra facial areas. For more than three decades it has been used in medical devices such as plates, screws, intraosseous and soft tissue implants, and as a biodegradable vector for drugs, in sutures and stents. The present article is aimed at presenting a literature review on the indications, application method, and complications of the use of PLLA.
