When the iphone 5s camera photos are flipped does it distort the image?

When taking pictures with my iphone I noticed that it flips my pictures and makes my whole face look asymmetrical but when I use my Imac front facing camera it does not flip the photos and my face is symmetrical. I'm really tripping out on this because I know a camera can't make you look better than what you really look like so I'm guessing its the iphone camera is distorting my facial features.

IPhones have tiny lenses, so it is entirely possible that defects are adding undue distortion. A defect of similar size on a regular camera lens might go unnoticed.

Regardless, holding a camera too close (i.e. At arm's length) adds a different type of distortion called "perspective distortion":

Phone cameras are generally wide angle lenses (cf. The 35mm, 24mm, and 19mm images). Portraits tend to look better with the camera at least one body length away.

The image sensors on phone cameras can also suffer from "jelly shutter", though mainly from motion along the long axis of the phone.

And not to be mean, but it is also possible that your face isn't symmetrical. Katie Holmes and Holly Hunter come to mind, the former for her smirky smile, and the latter is known for talking out of one side of her mouth. (Even Pixar knows this-watch The Incredibles and pay attention to Helen's mouth.)

It is probably more likely that you find your non-reflected image to be unusual, which is fairly common.
