This formulation includes aloe vera leaf extract and berry blossom complex to brighten and moisturize your skin. On top of this there’s the fact that, at the end of the day, you are still relying on people to do the right thing. Paula’s Choice’s sunscreens always add the ‘drug info’ on top as it’s done in the US. In the EU, that isn’t the norm.

So both the international standard test for SPF labelling (the ISO 24444 test) and the FDA test (which is very similar) still use in vivo tests on actual human beings. This applies to most places worldwide, including the US, South Korea and Australia. I think this is why we see a lot of sunscreens on the market where they have some really cool new filters, along with some older filters that people aren’t really that into anymore like octinoxate and oxybenzone, and that list doesn’t make a lot of sense if it was actually designed from scratch.
As mentioned, the people wearing sunscreen on a daily basis aren’t doing so for health reasons, but instead for vanity. And where vanity is concerned, UVA protection should be paramount.

It’s also to do with how these cameras work. They use specific UV wavelengths, not the entire spectrum of erythemal UV (which is what’s used for SPF). If you have a sunscreen that happens to be really biased towards protecting against that particular UV wavelength, then it’ll be really dark. If you have one that’s particularly not biased towards that wavelength, it might be really light. But overall, the two sunscreens could end up working around the same. The way that seems to work the best is by making special plates that mimic human skin, so when the sunscreen applies it dries on it just like it would on skin. Yoon says that Korean sunscreens have access to more and newer UV filter ingredients compared with sunscreens in the US, where the Food and Drug Administration (FDA) has been slower to test and adopt newly developed filters. It only tells you where you spread the sunscreen, and possibly whether it’s gotten lighter or darker with the same sunscreen. But you can’t compare between different sunscreens – the darkness can’t tell you if it’s SPF 15 or SPF 100.
Purito Centella Sunscreen became one of the top-rated sunscreens, according to bloggers, skincare professionals, writers and more. However, there was a scandal with Purito sunscreen that had everyone wondering if they could trust any claims made by sunscreen companies. Pissavini M, Tricaud C, Wiener G et al., Validation of an in vitro sun protection factor (SPF) method in blinded ring‐testing, Int J Cosmet Sci 2018, 40, 263-268. DOI: 10.1111/ics.12459 PURITO infuses many of its products with the cult-favorite ingredient centella asiatica for good reason. Also known as cica, Indian pennywort and gotukola, the plant offers many skin care benefits ranging from improving skin’s oil and water levels to increasing elasticity and soothing inflamed skin. This ingredient is particularly helpful for those with acne-prone skin as it helps in speeding up the healing process and in preventing scarring. In targeting common grievances such as greasiness and white-cast residues, top Korean sunscreens aim for a lightweight and invisible finish that makes them suitable for most consumers, especially people of colour. Take the Missha Soft Finish, which is perfect for oily skin as its powder-like texture is light and doesn’t leave a shine.

The low-viscosity fluid makes it comfortable and smooth to apply and your skin will look radiant and fresh when you have it on. Wong M. Purito Sunscreen and All About SPF Testing. Lab Muffin Beauty Science. December 10, 2020. Accessed October 31, 2023. With this in mind, Purito sunscreen got a big following because it included skincare ingredients, in addition to having sun protection. Purito had glycerin and hyaluronic acid, and users said they could easily layer the sunscreen with their makeup.
There is the possibility of the newer test being wrong and the label being correct, and I’ll go into some of the possible reasons for this later on. But I think most people now feel like there is enough evidence to be more cautious. European sunscreens have had SPF issues as well – there was a famous case with ISDIN, and 15% of sunscreens tested fell short of their label claim in consumer tests. But if you do want to go beyond the SPF label, here are some of the things that point towards a more reliable sunscreen despite all of this uncertainty: I’ve actually spoken to the maker of one of the most popular UV cameras, the Sunscreenr, and he says that no, you cannot tell the SPF from how dark it is, as the camera is qualitative and not quantitative. There’s also the cost of the sunscreen ingredient. If you want to cover the whole spectrum with one or two filters and you don’t want to go with a mineral sunscreen, then you pretty much have to use some of the newer broad spectrum filters.

Users say they like that they don’t get any burning or stinging, and the product doesn’t flake off at all. This sort of thing has happened with all sorts of sunscreens from all over the world before, from both big and small brands – where later testing didn’t get the SPF that’s claimed on the label. Small changes in the production of the sunscreen can also affect the SPF value. There’s usually some testing for consistent composition – for example, to make sure there’s actually 5% avobenzone every time – but again, there are lots of other things in the formula that can change that SPF. These results are even more incredible because the study was done in the 90s, using a 90s sunscreen that was SPF 16 with 8% octinoxate and 2% avobenzone. And this was done in Queensland in Australia, where there’s a LOT of UV. So even if your sunscreen application isn’t optimal, you are still getting a lot of protection.I did some research, including on Reddit, and found that before the SPF scandal people loved Purito because it felt like a lightweight moisturizer, and it didn’t leave a greasy residue. I hope you enjoyed this deep dive into some of the issues around SPF. This only really just skims the surface, but hopefully the complexity of the whole situation makes a lot more sense now!
