Social media has been a blessing and a curse. On the one hand, experts (scientists, doctors etc.) can become far more prominent – on the other hand, misinformation endorsed by an expert carries more weight and causes more harm than if there’s no authority behind it. Unfortunately, social media algorithms also reward churning out content quickly, regardless of accuracy. Hot …
I recently asked on my Instagram stories about cleansing myths, and I got back tons of replies! So here’s some cleanser mythbusting – unfortunately I couldn’t fit them all in this one post, but there’ll be a follow-up soon. A word of warning before we begin: the answer to a lot of these is going to be “it depends”. I …
Warning: Very nerdy content ahead! If you’ve been following sunscreen discourse (apparently this is a thing now) you’ll know that mineral sunscreens mostly work by absorbing UV and only scattering a small amount, in the region of 4-5% across the range of UV. This was quantified in a pretty commonly cited 2016 paper by Curtis Cole, Thomas Shyr and Hao Ou-Yang, “Metal …
The myth that “60% of what’s applied to your skin is absorbed into your bloodstream” is one of my pet peeves. It’s so far from the truth, and it’s cited with such an air of authority that it really ticks me off. It also tends to be cited by the sorts of people who push “non-toxic” products, which is very …
In case you haven’t already heard, the 2021 edition of “This Anti-Cancer Product Is Giving You Cancer” is that there’s been benzene found in a bunch of sunscreens. How much should we be freaking out about this? I did an Instagram post on this already, but I thought I’d elaborate a bit more. The video is here on YouTube, scroll …
There are so many myths around mineral or physical sunscreens – the ones with zinc oxide and titanium dioxide – and how they’re supposedly better than chemical sunscreens with scarier names like oxybenzone and octocrylene. And it’s usually zinc oxide that gets all the hype. Some of these advantages are true… but so many are just myths. And a lot …
There’s been a recent study published about the sunscreen ingredient octocrylene turning into benzophenone over time. According to the paper, “benzophenone is a mutagen, carcinogen, and endocrine disruptor”. I wasn’t going to do a proper analysis of this paper because it only really got lots of attention in France and not many other places, but then I saw that I …
Being the “sunscreen nerd” person, I get a lot of questions about unusual sunscreen products and whether or not their claims work out. Last time I talked about the Colorescience powder sunscreen and the Skinnies “pea-sized amount” claim. Related post: Do They Work? Colorescience SPF Powder, Skinnies “Pea-Sized Amount” (with video) This time I’m talking about two more products that people …
