A highly photostable oil-soluble filter with absorption across UVB and UVA wavelengths. It also helps stabilize less photostable filters in a multi-filter sunscreen system.
Why we tier this moderate
2 cited papers across 1 country. The mechanism is well-described and there's at least one controlled trial in the literature, but we tier this Moderate rather than Strong to stay honest about how many specific papers we cite directly.
