Novel Synthetic Dermal Fillers Based on Sodium Carboxymethylcellulose: Comparison with Crosslinked Hyaluronic Acid-Based Dermal Fillers

The data here demonstrate that it is possible to duplicate the rheologic properties of commercial XLHA fillers using CMC/PEO at different polymer concentrations to formulate improved dermal fillers. All of the dermal filler formulations prepared can be easily injected through 30-gauge needles.
