This was a randomized, no-treatment-controlled, evaluator-blinded, multi-center study to evaluate the effectiveness and safety of Restylane Defyne in the chin for augmentation and correction of chin retrusion.
This study was designed to enroll and randomize approximately 140 subjects in a 3:1 ratio of treatment to Restylane Defyne or no-treatment-control, including at least 21 subjects of Fitzpatrick skin type IV through VI. All randomized subjects were to have a Galderma Chin Retrusion Scale (GCRS) score of 1 (Mild) or 2 (Moderate).
Eligible subjects randomized to receive treatment were injected by the Treating Investigator at Day 1. The method of injection was at the discretion of the Treating Investigator. A sufficient amount of product was injected to achieve optimal correction of the chin, in the opinion of the Treating Investigator and subject. Optimal appearance was defined as at least 1 GCRS grade improvement from baseline and the best correction that could be achieved as agreed by the Treating Investigator and the subject.
At the 48-week visit, after all study procedures for the visit were completed, treated subjects had the option of receiving an additional treatment if optimal aesthetic improvement was not maintained with Restylane Defyne. Non-treated control subjects also had the option of receiving treatment with Restylane Defyne in the chin at Week 48. If an optional treatment was performed, a safety follow-up visits were scheduled
