A highly efficient, photostable oil-soluble UVB filter. Its strong absorption means a relatively small amount can contribute substantial SPF, while separate UVA filters complete broad-spectrum coverage.

2 cited papers across 2 countries. 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.
