Forehead crease I've seen people asking why the forehead crease in pictures exists, because it looks so terrible. However, I don't think I've seen it explained. This is why: as you gain weight to your face it can settle on your brow, making you look more masculine and making your eyes smaller and more square and the fat from your eye brow area overhangs and covers your eyelid (you give yourself a hooded eye). By raising your brow you can try to minimize this masculine, squared eye look.  People who raise their forehead like that are generally insecure about their eyes. People who are born with small or square eyes can be quite beautiful, because it would compliment the rest of their natural face. People who make this problem for themselves, no.
