It's also highly stable and non-irritating. It protects against UVB, UVA II, and UVA I almost uniformly, and is considered to be the broadest range sunscreen available today. The first main difference is that while TiO2 gives a nice broad spectrum protection, Zinc Oxide has an even nicer and even broader spectrum protection. It's definitely one of the best UV-filter agents we have today, especially in the US where new-generation Tinosorb filters are not (yet) approved.

The English translation is, so far it looks like sunscreens with nanoparticles do stay on the surface of the skin where they should be.Īll in all, Titanium Dioxide is a famous sunscreen agent and for good reason, it gives broad spectrum UV protection (best at UVB and UVA II), it's highly stable, and it has a good safety profile. A 2009 review article about the safety of nanoparticles summarizes this, "to date, in-vivo and in-vitro studies have not demonstrated percutaneous penetration of nanosized particles in titanium dioxide and zinc oxide sunscreens". But do not panic, these are concerns under investigation.

Once absorbed they might form unwanted complexes with proteins and they might promote the formation of evil free radicals. The main concern with nanoparticles is that they are so tiny that they are absorbed into the skin more than we want them (ideally sunscreen should remain on the surface of the skin). The itsy-bitsy Nano-sized particles improve both spreadability and reduce the whitish tint a lot, but unfortunately, it also introduces new health concerns. The cosmetic industry is, of course, really trying to solve this problem and the best solution so far is using nanoparticles. Sunscreens containing Titanium Dioxide are often hard to spread on the skin and they leave a disturbing whitish tint. The disadvantage of Titanium Dioxide is that it's not cosmetically elegant, meaning it's a white, "unspreadable" mess. Regular sized Titanium Dioxide also has a great safety profile, it's non-irritating and is pretty much free from any health concerns (like estrogenic effect worries with some chemical filters). Its protection is very good between 290 - 350 nm (UVB and UVA II range), and less good at 350-400 nm (UVA I) range. Iron Oxides (Ci 77491, Ci 77492, Ci 77499)Īnyway, it doesn't matter if it reflects or absorbs, Titanium Dioxide is a pretty awesome sunscreen agent for two main reasons: it gives a nice broad spectrum coverage and it's highly stable.

Hdi/Trimethylol Hexyllactone Crosspolymer Vaccinium Angustifolium (Blueberry) Fruit Extract ,īis-Ethylhexyl Hydroxydimethoxy Benzylmalonate , The Radiant Defense Perfecting Liquid with Broad Spectrum SPF 30 launches today for $66, and will be stocked exclusively at /Trimethylol Hexyllactone Crosspolymer , "We usually don't use that much when applying a cosmetic product, which is why they shouldn't be used by themselves." (Most dermatologists recommend this route when it comes to tinted products with built-in SPF, too.) "In order to achieve the SPF labeled on a product, you need to apply enough," Joshua Zeichner, director of cosmetic and clinical research at Mount Sinai Hospital in New York City, tells Allure. I should note that before applying Radiant Defense Perfecting Liquid with Broad Spectrum SPF 30, I slathered on my go-to sunscreen for added protection. (Think of it less as a tinted sunscreen and more as a supercharged, moisturizing skin-care powerhouse.) When it came to road-testing the product, I began during the dog days of summer - as good a time as any, right? - and while the texture was heavier than I had expected, the neutral undertones seamlessly blended into my warm, light-medium complexion with an even, soft-matte finish. As for how the brand determined the shade range? A Rodan + Fields spokesperson tells Allure that the product was tested "among an inclusive group of consumers" with "a diverse range of skin tones."
However, you can always apply your favorite foundation over Radiant Defense if additional coverage is desired. "We're a skin-care company - not a makeup company," said Stoddard.
