I guess this is the reason why the sunscreens from haruharu are now suddenly available in amazon
BEMT is the first new ingredient allowed by the FDA since the 1990s. It's meaningful but a very narrow decision. The FDA still has not approved any of the following sunscreens that have been widely used outside of the US, in some cases for decades:
- DHHB / Uvinul A Plus
- EHT / Uvinul T150
- MBBT / Tinosorb M
- Iscotrizinol / Uvasorb HEB
- Drometrizole trisiloxane - Mexoryl XL
- Methoxypropylamino cyclohexenylidene ethoxyethylcyanoacetate - Mexoryl 400
- Polysilicone-15 - Parsol SLX
- Disodium phenyl dibenzimidazole tetrasulfonate - Neo Heliopan AP
- Tris-biphenyl triazine - Tinosorb A2B
- Phenylene bis-diphenyltriazine - TriAsorB
- Diethylhexyl syringylidene malonate (photostabilizer)
If you live in the US, you are quite literally taking a risk with your health using US-made sunscreens. Luckily brands like Beauty of Joseon (Korean) and many others are readily available through sites like Yamibuy.
certain long clothes allows for skipping sunscreen entirely in perpetuity
Would have liked to hear about the safety profile for marine life that this has compared to other chemical sunscreens.

European sunscreens are safer than American (2024)
Bemotrizinol is the ingredient being discussed.
If you're looking for a specific product to try, check out Ombrelle and also La Roche-Posay's Anthelios line. I share this as a Canadian (bemotrizinol has been available here for years), but check the ingredients because it may vary by country because of regulations.
Aside: I did a bunch of sunscreen research some time ago for my family. I like the non-absorbing/non-reactive aspect of mineral screens but settled on a chemical screen and bemotrizinol seemed favoured but we landed instead on the Kinesys brand of sprays which we love because they're very waterproof and sweatproof in our experience but they feel like almost nothing. YMMV.
