This allows your muscles that elevate your eyebrows to work with less inhibition. This is how the Botox brow lift works. Botox weakens the muscles between your eyes and around your eyes to allow the frontalis muscle to lift the eyebrows up more. It takes experience to do this but knowing where to put the botox can make a huge difference with the results.
All parts of our bodies are supplied by muscle groups that work in opposition to each other for complete and proper function. In the arm, for example, we have the biceps muscles to flex the elbow and triceps muscles to extend the elbow.
In the forehead as well, there are muscles that elevate the brow and others that pull it down or depress it. The ones that pull the brow up cause the sideways lines of the upper forehead and those that pull the brow down cause the vertical frown lines above the nose.
By temporarily paralyzing the depressor function with injections of Botox above the nose and in the lateral eyebrow, the muscles the lift the brow can cause a subtle brow lift because their function is unopposed for about 4 months. For may patients this may be all they require and can avoid the need for a surgical browlift.
