How do we get the world to wear sunscreen?

Romain brings us a problem that should already be solved: how do you get people to wear sunscreen? The danger is obvious. The solution is cheap, available and easy to understand. Yet more than a third of people never wear sunscreen, and plenty of the people who do use nowhere near enough. So what’s going wrong? Is sunscreen too greasy, too annoying and too easy to forget? Is skin damage simply too distant to feel urgent? Or has the category spent too much time selling protection and not enough time making sunscreen desirable? It's an obvious solution to an obvious problem, but did we crack it? Check it out!
