When someone puts on makeup, there is no easy way to know why they've done it or why they made the decisions they did about their makeup. Answers to those questions might not even be clear to the makeup-wearers themselves! After a very long history of putting stuff on our bodies to accentuate our features, cosmetics - both the products and the idea of them - have taken on a good amount of baggage. So, its tough to know... Is it for the person wearing it? Is it for the people who are going to see the person wearing it? Is it for one by way of the other? This episode of Idea Channel approaches some of these questions, inspired by beauty and makeup tutorials found on YouTube and the tradition of person-to-person sharing of makeup knowledge.
