It’s also only fair to mention that many have questioned the motives of the INCID Decoder blog because the founder is creating a new sunscreen.

Firstly if your filters aren’t broad spectrum enough if they’re not covering a wide enough range of wavelengths, then you’re going to have to put in other filters in there to cover the rest. Something very broad spectrum like zinc oxide can be the only filter in a sunscreen. Testing was done by a third-party under the standards of Cosmetics Europe’s SPF Test Method (ISO 24444). US sunscreens have been tested the most by consumer groups, but US sunscreens have lots of problems. They use the older filters that aren’t as stable in the sun, they have a lower requirement for broad spectrum, and the filters tend to be more allergenic and irritating. But I am going to use the Sunscreen Optimizer to demonstrate a few things… The number of filters doesn’t tell you much
The differences between the SPFs that different labs get has always been a really big issue. Testing bias Purito put out a statement saying they’ve paused the sale of their sunscreens, and they said that they actually sent off their sunscreens for a test earlier but they still haven’t gotten the results yet. Part of this is because you can’t see how continuous the film is microscopically – it’s far too low resolution for that. So why are we still doing this annoying test? Can’t we work out SPF in other ways? Let’s talk about the issues with alternative methods. SPF from ingredients list? If you’re using a sunscreen and you’re getting burnt, or your pigment is getting darker, then it’s a sign that the sunscreen isn’t working for you. Whether it’s mislabeled, or not water resistant enough, or you’re just not managing to apply enough – whatever the reason is, it’s time to switch to a different sunscreen.

So if we can’t tell what’s going on from just the active ingredients, what if we take the whole formula and test it with a machine? The Soft Finish Sun Milk from Missha is a really interesting option if you’re interested in Korean sunscreen. It is a powder-base and it corrects your skin tone and texture, so it’s like sunscreen and a cosmetic product. But there is another really big reason why we’re so desperate to replace this test with an in vitro SPF test. It’s not very reproducible – in other words, testing the same sunscreen using this method doesn’t necessarily give you consistent results.But they can give you an idea of what sorts of things will change your sunscreen protection, and how the absorbance over different wavelengths will change, but DSM and BASF make it very clear that these are just a starting point for formulation. If you put in the percentages from a bunch of real sunscreens you can see that the SPF predicted can be wildly off. So if these models can’t give you an accurate prediction, then just looking at the filters in a sunscreen isn’t going to be any better!
Purito Sunscreen Scandal and What Happened With the Purito Sunscreen Scandal and
The reason some people prefer Korean skincare brands for sunscreen is that they tend to be light in texture and not so heavy and oily. On the other hand in many parts of Asia, daily sunscreen wear is very normal. That’s why there’s been a lot more effort into developing sunscreens that are as light and comfortable as possible, and generally that means cutting down the amount of filters. Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Active Agents), Ethylhexyl Triazone (Active Agents), Dicaprylyl Carbonate (Skin-Conditioning Agents), Titanium Dioxide (Active Agents), I think she has a good point with how Asian brands tend to produce different sunscreens with the same name, which leads to confusion for consumers (and IMO it erodes their reputation – I’m very disappointed that Shiseido does this) – it would be great if they didn’t do that! But I disagree with many of the points: Sunscreens are annoyingly complicated. The saying that the ingredients list can’t tell you the whole story about how a product works is especially applicable to sunscreens.In the month-plus since INCIDecoder’s blog post, Purito, Klairs, and Keep Cool have taken action. Here is what each brand has done in response to the controversy: Purito
