Summary Background Abobotulinum‐ toxin A is used extensively for the treatment of frown (glabellar) lines. Aims The aim of this study was to evaluate the efficacy and complications of a new injection technique and to assess the amount of satisfaction in patients with the frown lines. Methods This cross‐sectional study was conducted in 104 patients with moderate‐to‐severe glabellar lines. In the new technique by reassessing the responsible anatomic muscles of wrinkles, we tried to modify the injection technique of Abobotulinum‐toxin A to yield more favorable results. The range and severity of frown lines were assessed by a 4‐score test and a photograph taken before and 2 weeks after the injection. Patients were followed up to 180 days after injection. Results The response time of 87.5% of patients was within the first 48 hours and the remaining 12.5% showed the symptoms within the first week after injection. At 30 days after injection, the frown lines had disappeared in 88.5% of patients in static mode and 85.6% in mechanic mode. Maximum injection durability in the first 3, 4, and 6 months after injection was 82%, 52%, and 38%, respectively. The amount of complete satisfaction after 3 months was reported to be 86.5%. Conclusions This study indicated that the new injection technique of Abobotulinum‐toxin A could be beneficial in the treatment of frown lines with more satisfactory results, especially in those patients who were not contented with the present conventional method.
