- Device: STYLAGE Hydro
- Registration Number
- NCT05809739
- Lead Sponsor
- Laboratoires Vivacy
- Brief Summary
FLASH Study is a Post-Market Follow-Up PCMF designed to evaluate the tolerance and efficacy of STYLAGE Hydro by using a satisfaction questionnaire.
- Detailed Description
This is a prospective, in open, single arm and multicentric study designed to evaluate the tolerance and efficacy of STYLAGE Hydro.
Patients will be injected up to 2 mL of STYLAGE Hydro per area at each session. Three injection sessions 2 weeks apart are planned: one at visit 1 (D0), one at visit 2 (W2) and one at visit 3 (W4).
Proportions of subjects who are satisfied on the face 6 weeks after treatment initiation will be assessed. For each question of the questionnaire, the subjects who are satisfied are defined as subjects who rated "Somewhat agree", "Agree" or "Totally agree". Global aesthetic improvement according to independent evaluator and subjects' satisfaction will also be done during other visits. Safety parameters will be evaluated during the study period.
