A new product AmeaCell® , allows SVF extraction and ECM preconditioning in hypoxic conditions. Hypoxia significantly increased the adhesion of adipose derived stem cells and enhace their proliferation and differentiation. Objective: This clinical study aimed to evaluate safety and efficiency of this new procedure, over one year. Material and methods: The study was performed on 23 patients. After a liposuction and fat proceed, SVF and the matrix were extracted and preconditioned following Ameacell® procedure, then injected into wrinkles. Results were scored for WSRS and GAIS scales at 6, 12 months after surgery. Results: No serious adverse reactions occurred. Regarding efficiency, whatever the baseline, the Ameacell® procedure triggered an improvement of WSRS score in most patients after one year follow-up: 75% of patients when WSRS score at baseline 2; 83% of patients when WSRS score at baseline 3. This is in accordance with the GAIS scored by both investigators and patients. Conclusion: This one-year follow-up clinical study using Ameacell® procedure, exhibited an improvement of facial skin appearance.
