![]() ![]() Instead of nanoparticles, some natural sunscreen producers use “micronized” particles - basically, these are just slightly larger than nanoparticles (so larger than 100 nanometers).Ī particle must be 50 nanometers or less to penetrate a cell membrane, by the way, so micronized particles are safe. Fortunately, more recent research suggests that DNA damage from nanoparticles is not very likely. ![]() There has been some concern that these nanoparticles are small enough to penetrate cell membranes (normally, our cells recognize foreign material as an invader and block it out). teeny microscopic particles that are less than 100 nanometers in diameter) are typically used in sunscreen. By contrast, mineral sunscreens work by reflecting the UV radiation.īecause the application of mineral sunscreen ingredients leaves skin with a telltale white sheen, nanoparticles (i.e. Chemical sunscreens above work by absorbing UV radiation. Given the dangers of chemical sunscreens, the safest way to avoid sunburn is to use a natural sunscreen that contains “barrier” ingredients, such as titanium dioxide or zinc oxide.

That’s thanks to consumer demand–way to go, you guys! ❌ Oxybenzone is the really bad ingredient it causes cellular damage and endocrine disruption. ⚠️Octisalate and octocrylene are also both Okay Stuff, without major health concerns, but slightly worse than avobenzone. If you choose to use a chemical sunscreen, choose one with avobenzone as the primary active ingredient. ⚠️ Avobenzone is Okay Stuff, and the best of chemical sunscreen options.

The nontoxic sunscreens we call Best Stuff in this guide are free of the Bad Stuff we talk about in our skincare Guides–synthetic fragrances, PEG chemicals, propylene glycol, alumina, etc. ![]() In addition to the active ingredients, sunscreen also contains a number of inactive ingredients, some of which are concerning. Still, add this potential risk to the risk of vitamin D deficiencies, and standard sun safety doesn’t feel so safe! Some researchers even suspect oxybenzone to be the hidden cause of the increase in melanoma, although most studies have found no such link. Is Sunscreen Toxic?Ĭonventional sunscreen is loaded with chemicals, including parabens, well-established carcinogens, and oxybenzone, an endocrine disruptor that may generate free radicals when exposed to ultraviolet light.
