What is this ugly thing?

Don't worry about it~ it's not that noticable. If you look around, lots of people have those. It's just how your skin goes. It happened to my sister, who's 28. Her's is just like yours, and lots of other people have it, it's common. If you're like my sister, it won't get any worse. Just cover it up with foundation or get bangs if it bothers you. Hope it helps! =]
