What's Actually in Your Sunscreen
The good news: they dropped oxybenzone. The catch: what replaced it is at 30× the level Europe calls safe.
Credit where it's due: the big sunscreen brands quietly removed oxybenzone, the reef-killing, hormone-disrupting filter that Hawaii and Key West banned outright. We'll say that plainly, it's a real improvement. But the filters that replaced it haven't escaped scrutiny, and one of them sits in your bottle at up to thirty times the concentration Europe's own scientists call safe.
What got better
Banana Boat, Coppertone, and Neutrogena all reformulated away from oxybenzone, and their labels say so. Oxybenzone absorbs into your bloodstream at 250 times the FDA's safety threshold and is banned from several jurisdictions for reef harm. Removing it was the right call. A site that only ever cries 'toxic' would never tell you this, we will.
What replaced it
Homosalate is now the lead UVB filter, at 9–15% in these products. The EU's SCCS concluded it is not safe above 0.5%. That's a gap of up to thirty-fold between Europe's scientific finding and what the FDA permits. Octocrylene brings a second problem: it degrades inside the bottle into benzophenone, a carcinogen with zero allowed level in food and no safe harbor under California's Prop 65.
It's in your blood by day one
The FDA's own 2020 clinical trial found every chemical UV filter tested, homosalate, octocrylene, avobenzone, all of them, crossed into plasma above the safety threshold after a single application. The agency asked manufacturers for follow-up safety data. It still hasn't required them to finish it. If you want to skip the whole question, mineral (zinc oxide) sunscreens sidestep these filters entirely.
The teardowns
Banana Boat Ultra Sport SPF 50+ →
The lead UVB filter is at 9%, the EU's own science committee says safe maximum is 0.5%. Oxybenzone is gone from this formula; the 1,4-dioxane route from SLES is still there.
Coppertone Sport SPF 50 →
10% homosalate, the EU's science panel found the ingredient unsafe at 10% and recommended 0.5% as the maximum. The US permits 15%. The gap is 20×.
Neutrogena Ultra Sheer Dry-Touch SPF 55 →
The full 10% homosalate the EU says is unsafe, 10% octocrylene converting to benzophenone over time, and BHT, the antioxidant the UK restricted in 2024, as an inactive.
