The length of time the Botox will work depends on the amount injected and also the amount of muscle present. People with strong and larger muscle mass in the area of injection that are injected with just an average dose may not get as long as a result as people with smaller muscles and a larger dose. As to reducing the horizontal wrinkles of the forehead, Botox does have a potential to drop the eyebrows, again dependent on dose. It might require a small does of Botox at best, along with a filler for each individual wrinkle.
