Effective and Safe Repeated Full-Face Treatments With AbobotulinumtoxinA, Hyaluronic Acid Filler, and Skin Boosting Hyaluronic Acid.

Background: It is important to study full-face aesthetic combination treatments to establish well-founded individual treatment plans. Objective: To evaluate clinical outcome and perception of treatment with either abobotulinumtoxinA (ABO) or hyaluronic acid (HA) filler followed by repeated combined treatment with ABO, HA filler, and Restylane® Skinboosters (RSB). Methods & Materials: This study was conducted at four sites in Sweden, France, and Brazil and included subjects aged 35-50 years with mild/moderate nasolabial folds and moderate/severe upper facial lines. Monotherapy was ≤125 s.U ABO in at least two upper facial indications with optional touch-up or ≤1 mL HA filler in nasolabial folds/cheeks. At months 6 and 12, both cohorts received ≤125 s.U. ABO in upper facial lines with optional touch-up, ≤2 mL HA filler in nasolabial folds/cheeks (and other facial areas as applicable), and ≤1 mL RSB. Assessments included global facial aesthetic appearance and improvement, first impression, perceived age, wrinkle severity, satisfaction questionnaires, and adverse events. Results: Repeated full-face treatment with ABO, HA filler, and RSB was associated with better aesthetic outcome and higher levels of satisfaction than treatment with ABO or HA filler alone. However, even modest volumes of HA filler achieved good aesthetic outcomes and high satisfaction. Treatment of several indications was well tolerated. Conclusion: Aesthetic improvement and subject satisfaction was high and increased with each treatment. All treatments were well tolerated.
