I have noticed that people don't look at me in the face anymore. They usually look away when talking to me. When I'm with a group usually the person looks at everyone else while looking around and then quickly glances at me and then looks away. This wasn't a problem before acne.
I noticed this behaviour all the time, all the time. People probably think that I am stupid, but I see it all the time. People who do that are not social. Looking people in the eyes is regarded as a good social skill. They are projecting their hatred of acne onto other people. That you don't like acne is one thing. That you don't like people, because of acne, is completely something else.
