As the skin ages, it begins to lose its elasticity resulting in frown lines, wrinkling across the forehead, and an increasing heaviness in the eyebrows. Forehead lifts are an option if you have a sagging brow or deep furrows between the eyes. This procedure is usually done between age forty and sixty-five but can be performed at an earlier age. A forehead or brow lift tightens loose skin and removes the excess, forehead wrinkling and drooping brows are modified. When necessary, part of the muscle that causes vertical frown lines between the brows is also removed.
