I recently review a bunch of popular Korean sunscreens for a sponsored video, because most of you are heading into summer in the northern hemisphere. Conveniently I’m heading out of summer, so I’ve actually been trying out tons of sunscreens, and there are some really nice ones in this batch – including a few you’ve probably seen hyped up a …
I’ve talked a ton about sunscreen over the years, but I’ve found that on every sunscreen post I get asked questions that I’ve answered before, and I think it’s because I’ve gotten a lot of new followers (hi, welcome and thank you!). So I thought I’d do a post where I try to cover every sunscreen question that’s relevant to …
Here’s a special event for all the sunscreen nerds! I’ve teamed up with Jen of The Eco Well to organise the Sunscreen E-Summit, which is happening 15 May! This is a FREE event featuring some incredible speakers that you’d normally have to pay expensive conference fees to learn from, including academic researchers, ingredient supplier representatives, sunscreen formulators and regulatory experts. …

Instead of talking about sunscreen like I usually do, we’re going to dive into some of the things you can use to protect your skin apart from sunscreen (I can feel my sunscreen propaganda shillbucks slipping away right now). As much as we all love sunscreens, they are a bit of a pain in the butt. You have to apply them right, …
As a sunscreen connoisseur who tries out a lot of sunscreens, it always feel premature to make a list of my favourites. I try a lot of sunscreens but I feel like I can never get through as many as I’d like, because unfortunately I have just the one face. I did a list of my favourites at the end …
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.
