Effectiveness and Safety of STYLAGE® L Lidocaïne in the Treatment of Nasolabial Folds

STYLAGE® L Lidocaine is a CE-marked hyaluronic acid gel intended to fill skin depressions on the face by dermal injection. In this study, 50 healthy subjects between the age of 30 and 65, with moderate to severe nasolabial folds as assessed in live, who have given their informed consent and met all eligibility criteria, will be enrolled. Subjects will randomly receive injection of STYLAGE® L Lidocaine on one nasolabial fold and injection of an active comparator on the other nasolabial fold. A touch-up is possible if required one month after. Subjects will come to a total of 7 visits over a period of 12 months. Variation in severity score of nasolabial folds will be assessed in live and on photographs by independent evaluators. Variation in nasolabial fold depth, global aesthetic improvement, subject satisfaction, pain at injection site and safety will also be assessed.
