Well, a problem I have to deal with is acne / pimples. It has been an issue most of my life until the last few years. However, I still occasionally get a small pimple or two and invariably end up nicking them. The pictures look similar to what happens after one of my "not to good" shaves. As your skin care technique (pre and post shave routine) and shaving technique improves it becomes less of an issue.
