Background Restylane, a hyaluronic acid gel, has been widely used as a dermal filler in USA and European countries. This study was designed to study the safety and efficacy of Restylane as a non-permanent dermal filler for facial augmentation therapy in China for the correction of nasolabial folds during a follow-up period of 6 months. Methods The study consisted of a screening visit, a baseline visit during which injection with Restylane was given, and follow-up visits after four weeks, three months and six months. The efficacy was subjectively assessed by comparing the treatment results between pre-treatment and post-treatment. Adverse events were analyzed by severity and duration. Results At six months post-baseline, the subjects and the investigators＇ independent assessment score of Wrinkle Severity Rating Scale was decreased. Global Aesthetic Improvement Scale was considered to have improved by over 90% in some cases. Adverse events related to product and injection was reported in 21.5% of the injections. A vast majority of the post-treatment reactions were mild. Conclusions The efficacy of Restylane for nasolabial fold in a Chinese population was excellent. Restylane was well tolerated and no systemic reactions or other safety concerns were raised.
