The use of Botulinum Toxin is frequent in non surgical cosmetic procedures. Many aspects, though, still need clarification such as patient types and the duration of effect. By grouping the patients in different muscle pattern, the duration can be predicted and informed to patients. These groups consist of kinetic, hyperkinetic and hypertonic patterns. The kinetic pattern indicates that patients present a concordance with facial expression and emotions and they will probably need only one treatment per year. The hyperkinetic pattern refers to patients who do not move their muscles according to their mimicry. Facial muscles contract faster and the duration of the treatment will vary from 4 to 6 months. The hypertonic pattern is found in those patients that are unable to relax their facial muscles and the duration may be only from 2 to 3 months. That makes the treatment disappointing both for patients and injectors. By understanding the muscle behavior, the patient approach and their grouping according to specific muscle patterns, enables the prediction of duration and guidelines to future treatments.
