The differences between the SPFs that different labs get has always been a really big issue. Testing bias 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. 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: While that left many people feeling pretty upset, it’s actually a common occurrence with sunscreens, unfortunately.Note: The US Consumer Reports tests seem to use only water resistant sunscreens and test the water resistance SPF rating (similar to what’s required for the SPF label for any water resistant sunscreen), which includes an additional water soak test. The other consumer tests I looked at for this video (HK, Australian NZ) seem to have done a straightforward SPF test from what I can gather – the tests sometimes aren’t described in a lot of detail outside of the paywall.) Fraud happens One thing I find helpful when I’m worrying too much about sunscreen – whether my sunscreen is reliable, whether I’m using it correctly – is remembering the results of the Nambour study.

So with all of these issues with in vivo SPF testing, that’s why I really think you do need two in vivo SPF tests to raise significant doubt over an SPF label claim. That’s what Judit says in the INCI Decoder blog post as well – if we only have one, then it’s really hard to say whether it’s just an issue with inter-lab reproducibility, or if there’s actually a problem with the sunscreen. 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.While it was gaining popularity, people started reporting that they got sunburned while using Purito. Users started to say that they were reapplying often and using it as they were instructed and still suffering from burns.

The problem is human skin. You apply the sunscreen and the sunscreen interacts with your skin, and then your skin and the sunscreen film go out and interact with UV. So you still haven’t taken into account the whole equation. The fact that this happened with Neutrogena and La Roche-Posay I think, isn’t a sign that these brands can’t be trusted or that any sunscreen that tests below the label claim must be lying. These are two western brands that I consider to be two of the most trustworthy brands in sun protection, and they always go above and beyond to develop high protection sunscreens. Persistent Pigment Darkening tests use UVA radiation to cause a persistent darkening of the skin, which is tanning. 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.
