The efficacy and safety of a monophasic hyaluronic acid filler in the correction of nasolabial folds: A randomized, multicenter, single blinded, split‐face study

Abstract

Despite a number of different rheological properties, monophasic HA is noninferior to biphasic HA in the treatment of moderate to severe NLFs for 52 weeks. Therefore, monophasic HA provides an alternative option for NLFs correction.
