1,4-Dioxane Ban for Beauty Products? (With video)

Dioxane video

If you’ve ever looked up sodium laureth sulfate (SLES) and sodium lauryl sulfate (SLS) in a clean beauty app, like me, you might be surprised to find that SLES is dirtier than SLS. These apps are terrible and based on pseudoscience: SLS and SLES are both safe in your products. But if you’re a skincare nerd, you’ll know that SLS …

Impressively Bad Skincare Science: Matter of Fact (with Video)

Matter of Fact thumbnail

You might’ve seen Matter of Fact skincare all over social media lately. Their star product is a vitamin C serum, and they’ve been doing a lot of sponsorships with influencers, particularly the ones that come across as “sciencey” (with a science background and/or make scientific skincare content). You might’ve been surprised to see me in one of their influencer ads …

The Cost of Misinformation in the Beauty Space (Ventech Talk)

Ventech Beauty Misinformation

This was a talk I gave on 15 September 2021 for Ventech’s panel on Scientific Literacy and the Price of Misinformation. I talked about my insights on debunking myths over the last 10 years of Lab Muffin (yeah I’m old), how there’s financial incentive for many brands to bust beauty myths and communicate science, and the larger public health implications …

Will Benzene in Sunscreens Give You Cancer? (with video)

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.

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 …

Octocrylene Causes Cancer? and I’m Propaganda Now (with video)

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 …

Do They Work? Evy 6-Hour Sunscreen, Dermablend Drops in SPF

Evy & Dermablend: Do They Work?

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 …

Sneaky Marketing? The Inkey List Succinic Acid Acne Treatment

The Inkey List Succinic Acid Acne Treatment

The Inkey List are a brand that I generally quite like (well not anymore, now that I’ve seen their response to me raising this issue, and some of their other practices). They’re probably the main competitor to The Ordinary, which I also quite like. Both brands have lots of products, and many of them work well on my skin. They’re …
