This post is sponsored by Ulike. I did a deep dive into the science behind red light a little while back. Since then, I’ve been trying out more products and the Ulike ReGlow LED mask (use code MUFFIN for $100 off) has been one of my favourites so far. It has great specs, along with really user-friendly design features that …
Does retinyl palmitate in sunscreens increase skin cancer? This is a myth that’s been promoted a lot by clean beauty organisations like the Environmental Working Group (EWG), especially in their annual sunscreen guide. More recently, this was included as the first point in toxicologist Dr Yvonne Burkart’s video: “You’ve been lied to about sunscreen: Toxicologist reveals 6 things you should …
Here’s a growing directory of resources on sunscreen myths. They’re written as truths instead of myths, except where explicitly called out. These are mostly secondary sources, by me or other science communicators – most cosmetic science studies need to be interpreted with nuance to be useful. Also check out this sunscreen FAQ, and my Basic Skincare Guide eBook which goes …
You might have seen that Hawaii has banned certain sunscreens that have been linked to coral bleaching. In particular, it’s the organic “chemical” sunscreen ingredients oxybenzone and octinoxate that have been banned. It sounds like a great victory for the environment, right? But if you search a little past the headlines, you’ll find that there are actually a lot of …

This is a bit complicated to untangle, given the relative lack of data and the huge diversity of red light products. So this post is somewhat speculative – but I hope it’s helpful if you’ve been wondering! Note: I’m …
I don’t know about you, but over the last few years with existential pandemic and climate change stress, working from home and an ADHD diagnosis, my daily life routine has kind of gone out the window. I keep losing track of when I last changed my sheets, when lunchtime is, when I should go to sleep and whether I’ve taken …
Red light is everywhere – you’ll see it used by celebrities, skincare influencers, and biohackers (not sure why male wellness influencers get their own special name). What does it do, and which products actually work? Let’s dig into the science behind red light therapy, or photobiomodulation. The video version of this post was part of a 3-way collaboration with Becky …
The most controversial topic in Dr Andrew Huberman’s skincare episode is probably sunscreen safety, which is hugely misunderstood even by scientists and medical doctors. Much of the confusion comes from differing sunscreen regulations around the world, and the fact that “not safe” has different meanings in everyday, regulatory and toxicological contexts. This is part 2 of my articles responding to …
