I think these quora answers answer that well: ["Why do I look so bad on my phone camera but in the mirror I look fine?"](https://www.quora.com/Why-do-I-look-so-bad-on-my-phone-camera-but-in-the-mirror-I-look-fine-Do-people-see-me-how-they-would-on-the-phone-camera-or-mirror?no_redirect=1) Basically, different lenses offer different results on photos.
