Emervel for the Correction of Lower Face Wrinkles & Folds

A Multi-Center Study to Evaluate the Perception of Facial Expressions Following Correction of Wrinkles and Folds in the Lower Face Using Emervel® Classic Lidocaine and Emervel® Deep Lidocaine

This study is designed to

1. evaluate the naturalness of facial expressions in motion (2D video images), by treating investigator assessment
2. evaluate naturalness of facial expressions (photographs), by treating investigator assessment
3. evaluate perceived attractiveness and age of subject (2D videos), by treating investigator assessment
4. evaluate aesthetic improvement, by subject and treating investigator assessments
5. evaluate subject satisfaction
6. evaluate nasolabial fold (NLF) severity, by treating investigator assessment
7. evaluate marionette lines (MLs) severity, by treating investigator assessment
8. evaluate dynamic facial strain in animation using 3D digital photogrammetric analysis
9. evaluate all adverse events reported during the study.

Key Inclusion Criteria:

1. Seeking correction of bilateral NLFs: severe (i.e., bilateral WSRS = 3-4) or moderate (i.e., bilateral WSRS = 2-3) AND bilateral MLs: severe (i.e., WAS = 3-4) or moderate (i.e., WAS = 2-3).
2. Subjects of childbearing potential who agree to use medically accepted methods of contraception during the study and for 30 days following study completion.
3. Intent to undergo optimal correction of bilateral NLFs and MLs. Optimal correction is defined as the best possible aesthetic outcome as agreed to by the treating investigator and subject.

Key Exclusion Criteria:

1. Subject who presents with a severity of wrinkles or folds that require other treatments, e.g. laser treatment, chemical peeling, to achieve optimal correction.
2. Previous facial surgery, including aesthetic facial surgical therapy, liposuction or tattoo, in the treatment area.
3. Previous tissue augmenting therapy or contouring with permanent or non-permanent filler or fat-injection in the facial area.
4. Previous tissue revitalization treatment with neurotoxin in the facial area within 6 months before treatment.
5. Known/previous allergy or hypersensitivity to any injectable hyaluronic acid (HA) gel.
6. Known/previous allergy or hypersensitivity to local anaesthetics, e.g. lidocaine or other amide-type anaesthetics.
7. Known/previous allergy or hypersensitivity to gram-positive bacterial proteins.
8. Any medical condition that, in the opinion of the treating investigator, would make the subject unsuitable for inclusion (e.g. a chronic, relapsing or hereditary disease that may interfere with the outcome of the study).
9. Other condition preventing the subject from entering the study in the treating investigator's opinion, e.g. subjects not likely to avoid other facial cosmetic treatments, subjects anticipated to be unreliable, unavailable or incapable of understanding the study assessments or having unrealistic expectations of the treatment result.
