In life, many people especially like taking pictures, but sometimes people's faces are asymmetrical from left to right, and they also feel a little crooked. In fact, sometimes it may be because the camera angle is wrong, and sometimes it is really because their faces are a little crooked.
First of all, most people habitually chew on one side, which will cause one side of the masseter muscle to be too large, so that the face will be asymmetrical and the mouth will be asymmetrical. The second is malocclusion (the midline of maxillary teeth is not aligned with the midline of mandibular teeth) or mandibular deviation, and long-term abnormal occlusion leads to oral deviation. Generally, people with irregular teeth will have a crooked mouth and a crooked face. And sleeping on your side for a long time may also lead to.
When looking in the mirror, the brain beautifies itself and listens to unconscious feelings. But there is no scientific basis for lying. You in the mirror are presented by a mirror image of a plane, and the mirror image is formed by the signal transmitted to the brain through the pupil and the lens falling on the retina. If the brain can beautify, why not beautify other people or things in the mirror? It's all transmitted to your brain by mirror image using the same principle, and it's all the same.
