Comparison of 2.5% agarose gel vs hyaluronic acid filler, for the correction of moderate to severe nasolabial folds

Background Agarose gel filler is a natural hydrocolloid with a three‐dimensional structure similar to the extracellular matrix, with gel formed by hydrogen bonds and electrostatic interactions rather than through chemical cross‐linking or polymerization. Objective To determine efficacy and safety of 2.5% agarose gel filler for the correction of nasolabial folds. Methods In this split‐face study, efficacy, safety, and usability of 2.5% agarose...
