Safety and Effectiveness Evaluation of TEOSYAL® TPVM Versus COMPARATOR for the Remodeling of the Lower Face

Study Overview
=================
Brief Summary
-----------------
The clinical study is designed to prospectively evaluate the safety and effectiveness of TEOSYAL® TPVM when compared to COMPARATOR for the remodeling of the lower face

Detailed Description
-----------------
This is a prospective, randomized, blinded evaluator, multicenter, clinical study to evaluate safety and effectiveness of TEOSYAL® TPVM versus COMPARATOR for the remodeling of the lower face. Subject will be enrolled in the study based on evaluation of their chin retrusion severity. For the purpose of this study, all injections will be done by principal investigators (PIs) with several years of experience in aesthetic treatment. An external aesthetic and cosmetic surgeon will act as a BE to assess the performance of the treatment and the product based on photographs.

Willing to abstain from facial aesthetic procedures/therapies that could interfere with study evaluations Able to follow study instructions and complete all required visits. Having given its signed informed consent Exclusion Criteria: Known hypersensitivity or previous allergic reaction to any component of the study devices Known sensitivity to local anesthetics of the amide type, history of multiple severe allergies, or history of anaphylactic shock. History of active chronic debilitating systemic disease that, in the opinion of the investigator, would make the subject a poor candidate in the study.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in TCRS score between Baseline and 8 weeks after last treatment as assessed by the Blinded Evaluator | Non-inferiority of TCRS score change from Baseline for subjects treated with TEOSYAL TPVM compared to subjects treated with a COMPARATOR at 8 weeks after last treatment as assessed by the BE. TCRS (Teoxane Chin Retrusion Scale) is a validated 4-point scale assessing chin retrusion severity with 0 being None/minimal and 3 being Severe | 8 weeks |
