About

The aim of this study is to evaluate the safety and effectiveness of pain relief of modified sodium hyaluronate gel for injection when used for the correction of moderate or severe nasolabial folds.

Full description

One hundred and thirty patients were enrolled and there two sides of nasolabial folds (NLF) were randomized to receive HA with lidocaine or HA. The primary outcome was immediate visual analogue scale (VAS) of pain evaluated after injection for both NLF sides. Secondary outcomes including VAS pain, wrinkle severity rating scale (WSRS), global aesthetic improvement scale (GAIS) and AE were observed at 1, 3, 6, 9, 12 follow-ups.
