Condition or disease
Correction of Nasolabial Folds and Lip Augmentation
A Multicenter, Evaluator-Masked Study to Assess the Efficacy and Safety of Mentor's CX002 Dermal Filler Medical Device, When Applied as an Intradermal Implant for the Correction of Facial Wrinkles and Lip Augmentation (CX002 Dermal Filler Protocol)
Study the safety and efficacy of CX002 when applied to the NLFs or lips. [ Time Frame: 1 year ]
The primary aim of the study is to assess CX002, with respect to safety and efficacy during the six months following treatment, in two subject cohorts:
When applied as an intradermal implant for the correction of facial nasolabial folds (Nasolabial Fold Cohort). Nasolabial folds were chosen as the fold/wrinkle for treatment as they are often the most severe facial wrinkles, representing a "worst-case" scenario
When applied as an intradermal implant for lip augmentation (Lip Augmentation Cohort)
