Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 two products according to the randomization list. 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 (M11/2), 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.

Three (M3), 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
