BACKGROUND: Poly-l-lactic acid has been used in Europe since 1999 for cosmetic purposes and in the United States since 2004 for the treatment of human immunodeficiency virus lipoatrophy. This paper aims to present the use of poly-l-lactic acid for the cosmetic purpose of restoring facial volume lost due to the aging process. METHODS: Twelve patients were treated in private practice between 2006 and 2012. The product was reconstituted in 5 ml of distilled water and mixed with 2 ml of xylocaine 2% and epinephrine at the time of injection. Individualized treatment was performed according to each patient's facial size and contour. We analyzed photographs taken before and after surgery as well as subjective evaluations made by the physician and patients. RESULTS: All patients were satisfied with the results. Adverse effects included 4 cases of ecchymosis at the injection site and 1 case of nodules in the periorbital region. CONCLUSIONS: Poly-l-lactic acid is another tool for restoring, correcting, and smoothing facial deformities.
