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. Ultrasun is is completely friendly for those with very sensitive skin.Īqua, Octocrylene, Alcohol, glycerin, butyl methoxydibenzoyl-methane, titanium dioxide, c12-15 alkyl benzoate, dibutyl adipate, pvp/eicosene copolymer, diethylhexyl butamido triazone, tocopheryl acetate, panthenol, butyrospermum parkii butter, bisabolol, lactoperoxidase, lecithin, superoxide dismutase, acrylates/c10-30 alkyl acrylate crosspolymer, bisethylhexyloxyphenol methoxyphenyl triazine, carbomer, disodium EDTA, ethylhexylglycerin, silica, sodium hydroxide, dimethicone.Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (Nano)īis-Ethylhexyloxyphenol Methoxyphenyl Triazineĭiethylamino Hydroxybenzoyl Hexyl BenzoateĬ8-22 Alkyl Acrylates/Methacrylic Acid CrosspolymerĪnyway, 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.
