Why do I look so different in photos than in the mirror?

So you know how the iPhone camera flips the photo or video after you take/record it? I look so different from the mirrored version, the way I see myself when I look in the mirror, and the way other people see me. It's so annoying! For example, I look in the mirror, my lips look full and even, you know, like symmetrical on both sides. But when I take a picture on my phone, it flips it, and my lips look uneven and so different! Why is that? I think I look pretty good and then I take a picture and I look just so weird. Is it just because I'm not used to seeing myself reversed or are my eyes playing a trick on me? Why is this?!

I hate when this happens to me too I think it's the flash on the camera that gets every detail of your face and makes you look uglier it's just the way it is that's why I love mirrors more cause they aren't as mean as the camera haha

It's because when you look in the mirror you are looking at yourself flipped. And that's what your used to seeing

Camera lies

Same goes here. I guess we just aren't photogenic.
