Brief Summary

this study was proposed to provide more scientific and objective data on the clinical and aesthetic effects of these two toxins (Dysport and Xeomin).

Detailed Description

Subjects will perform 6 (six) visits during the study:

Screening visit, performed 30 to 1 day before the visit 1, when eligible subjects will be recruited and first evaluations will be performed; visit 1, which is the baseline and when the injections will be performed; visit 2, 30 +/- 3 days after the injections, when evaluations will be performed; visit 3, 90 +/- 3 days after the injections, when evaluations will be performed; 4, 120 +/- 3 days after the injections, when evaluations will be performed; visit 5, 150 +/- 3 days after the injections, when evaluations will be performed.

Assessment of percentage (%) of responders, after 5 months of injection, to the effects of two BT-A preparations, Dysport® and Xeomin®, by measuring frontalis m. wrinkle intensity at maximum contraction, as measured by visual Wrinkles Severity Scale (WSS).
