There’s been a lot of fearmongering about chemical sunscreens. There were scary-sounding new stories – sunscreen absorbing into blood, killing coral reefs, zinc oxide being toxic, benzene in sunscreens… Related Post: Top 7 Sunscreen and SPF Myths I’ve covered most of these before, and they’re largely just the media taking things out of context and sensationalising them, partly for views, …
There’s a sort of industry secret with mineral sunscreens: a lot of them contain unregulated chemical sunscreens. Which isn’t always a big problem… but it also kind of is.
