One of the few organic filters with strong UVA coverage. Often stabilized with other filters.
Absorption ≠ harm
A 2020 FDA-led study detected avobenzone in blood above the agency's screening threshold. The FDA said this does not mean it is unsafe and asked for more data.
Evidence & sources
Some sunscreen filters are absorbed into blood after maximal-use application. Evidence: emerging. Known: Plasma levels exceeded the FDA's 0.5 ng/mL threshold that triggers further safety testing. Unknown: Whether these levels have any health effect.
