Avobenzone
Butyl MethoxydibenzoylmethaneSPF filter
Chemical UV filter with strong UVA coverage. Photostabilized in modern formulas with octocrylene.
What it does
Avobenzone is the most-used UVA filter in US sunscreens. On its own it degrades in sunlight, so modern formulas pair it with octocrylene or other stabilizers. Provides the long-UVA coverage missing from titanium-only mineral sunscreens.
