I hate my face when I'm not wearing any make up. My skin is pretty good (I rarely wash my make up off and I smoke) but my problem is my nose. It's kinda big and it looks even bigger when there's nothing in my eyes. I could easily live without foundation, but I don't think I could go out without eyeliner or mascara/fake lashes. There's nothing wrong with my eyes, but when they're big and black with make up, people don't notice my nose.
And this is me with my make up on. Huge difference.
