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. Vaccinium Macrocarpon (Cranberry) Seed OilĪnyway, 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. Hydrogenated Dimer Dilinoleyl/Dimethylcarbonate Copolymer A component called thymoquinone (it's the main component of the volatile oil part, but the fixed oil also contains some) is considered to give the seed its main therapeutic properties including strong antioxidant and anti-inflammatory abilities.Stearyl/Octyldodecyl Citrate Crosspolymer In Islam, black cumin seed was considered "a healing seed for all diseases except death”.Īs for modern research and chemical composition, the fixed oil from the seeds is rich in skin-nourishing unsaturated fatty acids ( mainly linoleic acid at 50 – 60% and oleic acid at 20%, but also contains some rare ones like C20:2 arachidic and eicosadienoic acids), amino acids, vitamins, and minerals. The seed has a very complex chemical composition (it contains both fixed and volatile oil) and is used traditionally for a bunch of "anti-something" abilities including antitumor, antidiabetic, antihistaminic, anti-inflammatory, and antimicrobial properties. The (fixed or non-volatile) oil coming from the black seeds of Nigella Sativa, a smallish (20-30 cm) flowering plant native to Southwest Asia. It's definitely one of the best, or probably even the best option out there for sun protection available worldwide. This seems to be true even if the skin is damaged, for example, sunburnt.Īll in all, if you've found a Zinc Oxide sunscreen that you are happy to use every single day, that's fantastic and we suggest you stick with it. But luckily, so far research shows that sunscreen nanoparticles are not absorbed but remain on the surface of the skin or in the uppermost (dead) layer of the skin. ![]() We wrote more about nanoparticles and the concerns around them here, but the gist is that if nanoparticles were absorbed into the skin that would be a reason for legitimate health concerns. Still, it's white and disturbing enough to use Zinc Oxide nanoparticles more and more often. Pinnell, it's slightly less white than TiO2. ![]() It leaves a disturbing whitish tint on the skin, although, according to a 2000 research paper by Dr. It's also often used to treat skin irritations such as diaper rash.Īs for the disadvantages, Zinc Oxide is also not cosmetically elegant. 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.
