During a brow lift, the muscles under the skin in the middle of the forehead that cause grooves or frown lines between the eyes, increased heaviness of the eyebrows and horizontal lines across the forehead can be reduced or released to help create a smoother brow. Sagging eyebrows are usually first noticed in people who are in their forties, and this may be the time when you first start to think about a forehead or a brow lift. Brow lifts can be performed under a general anaesthetic, but for this procedure, many surgeons use a local anaesthetic along with a sedative to make you drowsy, so that you remain awake but feel very little discomfort. Although there are different brow lift techniques, the two main options that are used are the original open technique and an endoscopic brow lift. Most people return to work after 7 to 10 days this can often be sooner if you have had an endoscopic brow lift. Private costs for brow lifts can range from approximately £3,000 to £4,000.
