How does Botox work?
What muscles move the brow?
In order to understand how a Botox brow lift works, we need to understand how the brow moves up and down. There are many muscles in the face and a few the move the brow. There are two major motions of the brow: up and down. The muscle the moves the brow up is located directly above the brow on the forehead. It connects the brow with the front of the scalp just under the skin. When this muscle is relaxed it with Botox becomes more difficult to raise the brow. Therefore this is not the muscle to treat when lifting the brow. To pull the brow down we use muscles between the brow (as when frowning) and muscles at the corners of the brow (as when smiling). When these muscles are treated with Botox they become relaxes and we are not able to pull the brow down.
