It is used to attenuate (reduce /hide) the expression wrinkles on the facial (face) muscles. These wrinkles In order to determine the mode of action of Botox at the level of the synapse, an effective stimulation is muscular contractions are a normal response for the nervous messages (commands) from the brain.
