It’s sunscreen season, and as you’d expect, there are lots of sunscreen articles coming out, full of common myths.
I’ve debunked a lot of myths about sunscreens before – sunscreens are toxic, you can make your own sunscreen – but this time I’m going to focus on incorrect advice from trusted media sources. These myths tend to be a bit harder to spot, and they have less obvious (but still bad) consequences.
I don’t entirely blame the people writing these articles because this is part of a larger problem with sunscreen misinformation from other trusted sources. In the video I go through articles from NPR, Vox, USA Today and The Mirror, explain what they got wrong, and what you should be doing instead, and discuss the other trusted sources with questionable info.
The full video is here. Here’s a very brief summary…
