Changes in Identity (the face)

People can change their identities in different ways for many reasons. Often, someone will change his or her identity to fit into a group. People may also change their identity to stand out of a group, or to prove that they are not something. This almost always leads them to another group that they also must conform to in some way.

On a different note, some people will change their physical appearance either to feel more confident, or to change the way they are perceived. This often happens in the form of plastic surgery. In particular, people who are always being looked at are pressured to look perfect, so they change details of their faces and bodies that they think are flawed.

Celebrities and common people alike also wear makeup--or, in the case of men, grow beards--to change or hide the part of their identity that is their face. Every circumstance is different in this situation; sometimes makeup enhances the natural features of the face, and sometimes it hides them. The same is true for beards.
Overall, many people will take certain measures to  change their face in order to present themselves differently. This can effectively change your identity in affecting the way you are seen by others and the way you see yourself.
