The use of poly-l-lactic acid in facial aesthetic surgery has been utilized for over a decade. More recently approved by the Food and Drug Administration as a stimulatory filler for the correction of shallow to deep facial lines, it is gaining popularity in the United States. The advantages of its use include its stimulatory action on collagen formation, the longevity of its effect, and the low side effect profile. Despite these advantages, meticulous preparation practices and injection techniques are paramount to achieving a satisfactory outcome. We review poly-l-lactic acid as a filler, along with its associated side effects, indications of use, and techniques of injection.
