Detailed Description

The study will evaluate non-inferiority in clinical improvement in the intensity of expression lines over 16 weeks of drug Botulift (Laboratório Químico Farmacêutico Bergamo Ltd.) compared with Botox ® (Allergan Inc.). So that the homogeneity of the group opted to use in female patients with glabellar wrinkles grade 2 (moderate) and 3 (severe) Scale Standard Facial Wrinkles, established by Honecker et al. (2003). The first area of the face perceived in mime is the glabellar complex, located in the space between the eyebrows, wrinkles eventually show (Almeida et al., 2010).

Patients will be evaluated at each visit, the doctor Principal Investigator and digital photos of the glabellar region at maximum contraction and relaxation will be obtained using the apparatus Visia (Canfield Imaging Systems, version 4.0.2) for further analysis by random team dermatologists.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
overall improved assessment of hyperkinetic facial lines in a state of relaxation and maximal contraction through the Honeck's scale and photographic images obtained by equipment Visia Digital Compexton Analysis (Canfield Imaging Systems, version 4.0.2)
Time Frame: after 30 days of application
The non-inferiority of T group compared to the group Co was demonstrated in evaluations in a state of relaxation and maximal contraction in the PP analysis population, because as defined for the study, the lower limits of 95% of the mean of these assessments (-2 , 7% and -5.4%) are contained within the non-inferiority limit set at -10%.
after 30 days of application

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame

Time Frame: during the 24-week period
The action of both treatments decreases over time and there is no significant difference between the two treatments.
during the 24-week period
Safety of both botulinum toxin A
Time Frame: during the whole period
The occurrence of adverse events was similar in both groups.
