My favorite sunscreen disappeared from the internet. Where did it go? A few years ago, social media videos convinced me to change my habits around sunscreen. I started buying sunscreen not from my local drugstore, but from the internet: Sunscreens from Japan, France, Australia, and South Korea. These products went viral on platforms like TikTok, where fans praised just how comfortable and effective international sunscreens were compared to their American counterparts. But then one day, those products disappeared from the internet in the US. I wanted to understand what happened to my new favorite sunscreen — and whether or not the US can ever catch up to the sunscreen in the rest of the world.
