Buttocks Volume Loss
Conditions
Brief summary
The purpose of this study is to assess the effectiveness and safety of Gana X, a Poly L-lactic acid filler for the aesthetic treatment of buttocks.
Detailed description
A screening visit will allow to inform and preselect the participants. On D0, baseline scoring, fringe projection acquisitions and photographs will be done before injection. Eligible participants will receive a first injection of the product. Immediately after injection, injector's treatment satisfaction will be collected. Investigator evaluator will collect Adverse Events (AEs) and Injection Site Reactions (ISRs) immediately after injection. A month and a half after initial injection (M1 and a half), clinical scoring, fringe projection acquisitions and photographs will be done before touch-up (if applicable). Participant's treatment satisfaction and injector's treatment satisfaction (if applicable) will be collected. A touch-up injection will be made if necessary, according to injector and participant opinion. Investigator evaluator will collect AEs and ISRs before and after touch-up if applicable. Six (M6), nine (M9), twelve (M12), eighteen (M18) and twenty-four (M24) months after initial injection, clinical scoring, fringe projection acquisitions and photographs will be done. Participant's treatment satisfaction will be collected. Investigator evaluator will collect AEs and ISRs.
Interventions
Injection in the deep dermis and subcutaneous layer of the buttocks on D0 (initial injection) and 1 month and a half after initial injection if necessary (optional touch-up).
