The eyebrows will, with time, progressively drop and come closer together over the nose. This results in an "angry," "worried," or "tired" appearance. As the brow descends, it often pushes skin onto the upper eyelid, contributing to "tired looking" eyes. Horizontal creases over the forehead develop and make the forehead look wrinkled and "old."
Up until the mid 1990's, browlift surgery required visible incisions or extensive surgery to hide the scars. The most common brow surgery, the coronal browlift, required a scar that extended from ear to ear over the top of the head. While this procedure worked well, it entailed a lengthy procedure and a long recovery period. Today's browlift is much faster.
