Summary

The purpose of this research study is to evaluate the safety and effectiveness of injection with DGE Injectable Gel (hyaluronic acid with lidocaine manufactured by Genzyme Biosurgery) as compared to injection with Restylane (a Food and Drug Administration (FDA) approved dermal filler) in patients undergoing cutaneous correction of the nasolabial folds (NLFs).

Detailed Description

This study included an Initial and a Repeat Treatment period. The Initial Treatment period was a subject and evaluator-blinded, randomized split face study in which subjects received DGE in one nasolabial fold and Restylane in the other nasolabial fold. Both safety and efficacy were evaluated. In the Repeat Treatment Period, participants received DGE in both NLFs. Safety was evaluated.
