RESUMEN
BACKGROUND: Combination treatments using hyaluronic acid (HA) fillers and botulinum toxin Type A (BoNT-A) are common in aesthetic medicine; however, this has been evaluated in only a few clinical studies. OBJECTIVE: To evaluate subject satisfaction, efficacy, and safety of BoNT-A (Speywood Unit; s.U) and a range of HA fillers for full-facial aesthetic rejuvenation. MATERIALS AND METHODS: A 6-month, multicenter, open-label clinical study, using BoNT-A (s.U) and 5 HA fillers to treat up to 13 facial zones. Subject satisfaction questionnaires were administered 3 weeks and 6 months after the last injection. Global aesthetic improvement and improvement on each treated zone as well as safety were evaluated. RESULTS: A high level of satisfaction was achieved throughout the study, with 96.5% of subjects at least satisfied with the full-facial aesthetic outcome at 3 weeks, and 92.9% at 6 months. More than 91% considered the treatment outcome to meet or surpass their expectations, and more than 94% would recommend the treatment to others. At Week 3, subject and investigator assessment showed aesthetic improvement for all subjects. The treatment was well tolerated. CONCLUSION: The combination of BoNT-A (s.U) and HA fillers results in high patient satisfaction and in an overall improvement of aesthetic outcomes and quality of life.
