These popular injectable treatments temporarily reduce the appearance of moderate to severe frown lines, known as the Elevens, forehead, frown, lines and Crow's Feet. They are also used to restore symmetry, lift the brow area and smooth wrinkles in the lip and neck areas. Treatments consist of injections into the facial muscles, effectively weakening the underlying muscle, so that it temporarily will not contract to soften and even fade deep lines and wrinkles.
