![]() So much so that Zinc Oxide also counts as a skin protectant and anti-irritant. 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. (We'd go so far as to say that these could actually make you look forward to applying SPF.Titanium Dioxide/Dioxyde De Titane (6.6%)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. Read on for our tried-and-true favorite body sunscreens. So, whether you choose a formula with bells and whistles or stick to a straightforward option, one thing is for certain: There's no excuse not to give your skin the protection it needs. The current generation of sunscreens is filled with amazing formulas that not only mitigate these common annoyances, but even impart additional benefits like luminosity, moisture, and a faux glow, to name a few. Yes, we're aware of the issues some sunscreens come cause, like leaving behind a white cast, greasy feel, or clogged pores, but the days of subpar sun protection products are mostly behind us. ![]() Tanzi recommends applying about a shot glass's worth of sunscreen for the entire body and a dime-size dollop for the face, and reapplication every two hours. Chemical formulas, on the other hand, penetrate the surface of the skin to prevent damage from the sun. Elizabeth Tanzi, MD, board-certified dermatologist and founder and director of Capital Laser & Skin Care in Chevy Chase, Maryland, has previously told Allure that these sit on the surface of the skin to deflect the sun's harmful rays. If you have sensitive skin or are pregnant, you'll also want to consider a mineral or "physical" sunscreen. New York City-based board-certified dermatologist David Colbert, MD, previously told Allure that this is what the American Academy of Dermatology (AAD) recommends because it is clinically proven to be a sufficient amount of protection to reduce the adverse effects of sunlight. Therefore, finding a good sunscreen is a must, and there are several factors that go into what makes a good sunscreen.įirst, you'll want your sunscreen (face or body) to be at least SPF 30. In case you need a refresher, ditching your sunscreen could lead to skin concerns like hyperpigmentation, inflammation, fine lines, and - worst-case scenario - skin cancer. Practicing proper sun protection techniques, like head-to-toe SPF protection on a year-round basis, prevents UV-related skin issues in the long run. No matter what the season or how much time is spent outdoors, protecting ourselves from harmful UV rays with one of the best body sunscreens is non-negotiable.
