A brow lift is a procedure that renews a more youthful, rejuvenated appearance above the eyes. Often the drooping brows, horizontal lines, and furrows can cause a person to appear angry, sad, and tired. People develop the creases and frown lines due to aging, stress, and/or muscle activity. In a brow lift, the muscles and tissues that cause the furrowing or drooping are removed or altered to smooth the forehead, raise the eyebrows and minimize frown lines.
