What exactly is "makeup shaming"?

When a beautiful woman walks into the room, all heads turn--men and women alike. There is just something about the beauty of a woman that makes everyone want to take a moment to admire, or maybe even to envy. Either way, it is still provoked by awe. And this is why women have always desired to have beauty. We all want this seemingly magical effect that beauty seems to have on others--especially men. We see how men fall over themselves to get the attention of the beautiful woman in the room. Sometimes it can be frustrating to watch. After all, it's just an image.
