![]() This was to try to convince them to add powders to the sunscreen monograph, so SPF powders would be recognised as over the counter drugs. Most of the brands I contacted gave me a really generic answer, but Colorescience directed me to some publicly available efficacy and safety data they submitted to the FDA. ![]() So I went off and emailed a bunch of powder sunscreen brands about whether they had data on how much they’d expect people to apply of their powder, and what protection people could expect. That’s pretty darn impressive for a powder sunscreen – clearly some of them can cling onto skin pretty well! But 2 mg per square centimetre is a lot of powder.

But when I was working on my video about reapplying sunscreen on top of makeup, I noticed that sunscreen powders do sometimes have high SPFs, and some of them even have water resistance – the Colorescience one is SPF 50 and 80 minutes water resistant. The problem that everyone always points out is that you can’t get enough powder on your face to get even protection. It would make reapplying on top of makeup really easy. Powder sunscreens are really promising – the idea that you can just dust powder on top of your skin and get enough sun protection is awesome. Colorescience powder sunscreenĬolorescience is a dermatologist favourite, and their most famous product is their powder sunscreen. If you have reasons to disagree, or if there’s evidence I’ve missed, share them in the comments. I could be wrong, but I’ve explained my reasoning here and what tests would actually convince me that these products work.

We’ve seen this again and again, where a small brand does something and proves that it can sell, then larger companies hop on the trend or buy out the smaller brand. Larger brands are less likely to take risks even if there is market demand. There are lots of innovations happening, and brands usually don’t make a lot of their information public for competitive or legal reasons, so you can’t really assume that something doesn’t work just because the information isn’t public – you really need to dig.Īnd it is usually smaller brands who are innovative. I try to keep an open mind about claims, because there are a lot of issues with sunscreens and it’s great to see scientists try to solve these issues. I like to talk to the company to try to understand what their reasoning is for their claim, and whether the claim makes sense based on what we know about how sun protection works. 3 Skinnies “Pea-Sized Amount” Sunscreen General note about unusual sunscreen claims
