These newer filters are excellent – the reason they’re not approved in the US is basically that the FDA is very slow at getting these new filters approved. They’ve recently reopened the case, but they’re asking for safety data based on animal testing and because of the animal testing ban, sunscreen companies can’t go and get this extra specific data. So there’s a bit of a stalemate in the US about approving these filters until newer non-animal tests are developed. But based on other safety data, they’ve been approved pretty much everywhere else including the EU and Australia.) I think when you have two in vivo SPF tests that agree and one that doesn’t, that’s when you can confidently say there probably is a problem somewhere, and the burden of proof switches. I don’t think there’s necessarily any wrongdoing on anyone’s part here – there are explanations that don’t involve that. My gut feeling is that it’s more likely than not there is some sort of issue with the sunscreen, and that can range from whether it’s just really not that robust or someone has straight up being fraudulent. It’s impossible to say where in the process this has happened and whose fault it is. Korean sunscreens are K-beauty’s hot trending product, with better protection, skincare benefits and more lightweight finishes reasons some people prefer them There are always new SPF boosting technologies coming out on the market and I’m not that knowledgeable about sunscreens, but here are two that I do know a bit about:

I’m really wondering about the waves this ‘scandal’ made, because, sunscreen ‘scandals’ happen. A lot. Every year. And nobody talks about that. I don’t say that to modify the seriousness of the whole thing, but to bring it into perspective. Sunscreen testing is rather susceptible to error. One cosmetic chemist told me that she just finished formulating a sunscreen, and it took her 6 months, even though she started with an SPF 30 base and just had to raise the SPF. So obviously protection isn’t just about the amounts of filters you put into it, because if it was then they’d be done in a day. I’ve been told that some of La Roche-Posay sunscreens have well in excess of their labelled SPF protection. The highest allowed in Australia is SPF 50+, but they go well beyond this. These issues can apply to the Purito test or the INCI Decoder test. Were they both really the Purito sunscreen? Did INCI Decoder accidentally get a fake tube? Did someone somewhere along the line accidentally use the wrong sunscreen? Like AMA Labs (allegedly) did someone just completely make up the numbers? It’s really hard to be sure without any extra testing.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? One thing I did notice in the INCI Decoder test was that the lab was told that the SPF would be around 20. I’m guessing when Purito did their test they told their lab that it would be higher, so this extra information might have influenced the results. General methodology issues As of February 2021, Purito issued a new statement. Their independent tests didn’t reach SPF50. They said they ended their relationship with their manufacturer, and their plan is to create a new sunscreen with a new manufacturing partner. Purito says they will test the products in Korea and overseas before it becomes available. Why Do People Love Korean Sunscreen?

Recently you might have heard that one of my former favorite sunscreens Purito Centella Unscented Sun tested at SPF 19, which is much lower than its labeled protection of SPF 50+. There were rumours that it didn’t match the label claim before, but until INCI Decoder published the two in-vivo SPF tests on their blog, a lot of scientists were saying that there wasn’t enough evidence yet to disbelieve the label. There are little differences between the regions with things like how reproducible the test has to be, and how many volunteers you have to use, but in essence the test is the same. It also goes the other way – one sunscreen tested in vivo on skin at SPF 20.3, but all four in vitro methods overestimated it at SPF 31.5 to 42.7.

Instead, I think it’s a reflection of issues with SPF testing and with batch variations and, in my opinion, a reflection of the robustness of some sunscreens – how consistently they perform over time in different conditions, which isn’t really captured by the current way of SPF testing. In 2016, Consumer Reports found that 23 out of the 60 sunscreens they tested tested at less than half their labelled SPF. 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:One of the reasons that some people said Purito had to be lying is that there were low concentrations of the filters. The problem with this is that yes, the SPF does depend on the percentages of the filters… but also on a lot of other things, like how well the formula spreads out the sunscreen actives in the final sunscreen film, whether there’s SPF boosters used. Your article was so helpful!, as well as thought provoking. One of my questions continues to be, what if the Purito brand sunscreen has regularly worked well for me?, which is the case. I don’t understand how people can have such different experiences with one product, unless as you mention different batches, working differently. Looking forward to the results! And thank you again Michelle! Reply All of PURITO’s products are made with natural ingredients to ensure its gentle formulations are suitable even for sensitive skin. However, the Korean brand understands that everyone’s skin care needs are different, so it also offers products for skin that’s extra delicate. PURITO releases unscented versions of its bestselling formulas including the Centella Unscented Toner, Centella Unscented Serum, Centella Unscented Recovery Cream and Centella Unscented Eye Cream. The Centella Unscented Toner boasts all the benefits of the original Centella Green Level Calming Toner. The unscented version is free of essential oils, which are often used for natural fragrance and antioxidant benefits but can also irritate and damage sensitive skin. With its low acidity level, the unscented toner is safe to use for sensitive skin. Powered by cica extract, its alcohol-free formula effectively soothes, balances skin’s pH levels and strengthens the skin barrier.
Purito Sunscreen Scandal and What Happened With the Purito Sunscreen Scandal and
Since a decent amount of time has elapsed since the INCIDecoder blog, I’m a lot less emotional and able to view the situation with a clearer head. 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.Apart from its Green Level Skin Care Line, PURITO also offers a Cica Clearing BB Cream in various shades. The multifunctional BB cream blurs blemishes, wrinkles and pores while brightening, soothing and providing long-lasting hydration. The Consumer Reports test replicates the official water resistance test used in many places (US, Australia, EU, Brazil etc.), so it isn’t a “made-up methodology” or “terrible science”– perhaps she’s less familiar with it because there’s no regulation for water resistance in Japan. Third party tests from ICRT organisations usually use valid methodologies (but with lower reliability due to sample sizes). 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. One thing that could be contributing to why it looks like there’s a higher fail rate for Asian sunscreens is that the consumer tests were conducted in an Australian lab. So that ethnicity difference could be an issue.
