The Claim
Under maximal use conditions, oxybenzone achieves significantly higher systemic plasma concentrations than avobenzone, octocrylene, or ecamsule, with geometric mean maximum concentrations exceeding 169 ng/mL, indicating greater dermal absorption potential for oxybenzone compared to these other UV filters.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When sunscreen is applied generously and frequently, oxybenzone enters the bloodstream at higher levels than avobenzone, octocrylene, or ecamsule, with average peak concentrations above 169 ng/mL.
See the scientific wording
Oxybenzone reaches significantly higher systemic plasma concentrations than avobenzone, octocrylene, or ecamsule under maximal use conditions, with geometric mean maximum concentrations exceeding 169 ng/mL across formulations, indicating greater dermal absorption potential for this specific UV filter.
Oxybenzone passes more easily through the outer skin layer than other UV filters because it is more oily, so more of it gets into the bloodstream and stays there longer, leading to higher blood levels.
What the research says
1 studyWhen people use sunscreen heavily and often, oxybenzone gets into the blood much more than other sunscreen chemicals like avobenzone or octocrylene — the study proved this by measuring blood levels in volunteers.
