PMMA (polymethylmethacrylate) fillers
(Artecoll®, ArteFill®, Artesense™, Artes Medical) are a type of permanent filler. Unlike temporary fillers, the immediate filling effect of PMMAs disappears rather quickly and, over time, gradual, but long-lasting correction is established. The Food and Drug Administration (FDA) approved PMMA fillers for the correction of facial wrinkles, such as smile lines.
Note: The FDA reviews and approves pharmaceutical fillers. However, some fillers may be used on an off-label basis, which means they have been approved for wrinkle correction in a given area only, or for some other medical indication, but not directly reviewed for a specific application. For a more detailed discussion of off-label uses of fillers, consult your plastic surgeon or dermatologist.
