Ingredient
Avobenzone
Avobenzone is the only FDA-approved chemical sunscreen filter that covers the full UVA spectrum (320-400nm). Most American daytime products rely on it for UVA protection — but it's notoriously unstable in sunlight and must be paired with photostabilizers like octocrylene or Tinosorb S.
Evidence Level
Well-established as a UV filter but with stability caveats. Degrades by up to 50-60% within an hour of UV exposure without stabilizers. Modern formulations pair it with octocrylene, bemotrizinol, or encapsulation technology to maintain efficacy through a day of wear.
